Brian Matthews (biochemist)
Brian W. Matthews is a biochemist and biophysicist educated at the University of Adelaide, contributor to x-ray crystallographic methodology at the University of Cambridge, and since 1970 at the University of Oregon as Professor of Physics and HHMI investigator in the Institute of Molecular Biology. He created hundreds of mutants of T4 lysozyme (making it the commonest structure in the PDB), determined their structure by x-ray crystallography and measured their melting temperatures. Starting from questions about the basis of "temperature-sensitive" mutations, his work has explicated much about the general energetic and structural effects of mutations in proteins. He also solved early structures of the thermophilic bacterial enzyme thermolysin, the helix-turn-helix DNA-binding transcription factor lambda Cro repressor, and the light-antenna bacteriochlorophyll protein. Beyond his contributions to biochemistry, Matthews is also known in the machine learning community for the Mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Barker, South Australia
Mount Barker is a city in South Australia. Located approximately 33 kilometres (21 miles) from the Adelaide city centre, it is home to 16,629 residents. It is the seat of the District Council of Mount Barker, the largest town in the Adelaide Hills, as well as one of the fastest-growing areas in the state. Mount Barker lies at the base of a local eponymous peak called the Mount Barker summit. It is 50 kilometres from the Murray River. Mount Barker was traditionally a farming area; many of the lots just outside the town area are farming lots, although some of them have been replaced with new subdivisions in recent times. History Mount Barker, the mountain, was sighted by Captain Charles Sturt in 1830, although he thought he was looking at the previously discovered Mount Lofty. This sighting of Mount Barker was the first by a European. Captain Collet Barker corrected Sturt's error when he surveyed the area in 1831. Sturt named the mountain in honour of Captain Barker after he was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermolysin
Thermolysin (, ''Bacillus thermoproteolyticus neutral proteinase'', ''thermoase'', ''thermoase Y10'', ''TLN'') is a thermostable neutral metalloproteinase enzyme produced by the Gram-positive bacteria ''Bacillus thermoproteolyticus''. It requires one zinc ion for enzyme activity and four calcium ions for structural stability. Thermolysin specifically catalyzes the hydrolysis of peptide bonds containing hydrophobic amino acids. However thermolysin is also widely used for peptide bond formation through the reverse reaction of hydrolysis. Thermolysin is the most stable member of a family of metalloproteinases produced by various ''Bacillus'' species. These enzymes are also termed 'neutral' proteinases or thermolysin -like proteinases (TLPs). Synthesis Like all bacterial extracellular proteases thermolysin is first synthesised by the bacterium as a pre-proenzyme. Thermolysin is synthesized as a pre-proenzyme consisting of a signal peptide 28 amino acids long, a pro-peptide 204 ami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Adelaide Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

United States National Academy Of Sciences
The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM). As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve '' pro bono'' as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. ... to provide scie ...

Machine Learning
Machine learning (ML) is a field of inquiry devoted to understanding and building methods that 'learn', that is, methods that leverage data to improve performance on some set of tasks. It is seen as a part of artificial intelligence. Machine learning algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning algorithms are used in a wide variety of applications, such as in medicine, email filtering, speech recognition, agriculture, and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Voronoi-Based Multi-Robot Autonomous Exploration in Unknown Environments via Deep Reinforcement Learning IEEE Transactions on Vehicular Technology, 2020.

Helix-turn-helix
Helix-turn-helix is a DNA-binding protein (DBP). The helix-turn-helix (HTH) is a major structural motif capable of binding DNA. Each monomer incorporates two α helices, joined by a short strand of amino acids, that bind to the major groove of DNA. The HTH motif occurs in many proteins that regulate gene expression. It should not be confused with the helix–loop–helix motif. Discovery The discovery of the helix-turn-helix motif was based on similarities between several genes encoding transcription regulatory proteins from bacteriophage lambda and ''Escherichia coli'': Cro, CAP, and λ repressor, which were found to share a common 20–25 amino acid sequence that facilitates DNA recognition. Function The helix-turn-helix motif is a DNA-binding motif. The recognition and binding to DNA by helix-turn-helix proteins is done by the two α helices, one occupying the N-terminal end of the motif, the other at the C-terminus. In most cases, such as in the Cro repressor, the second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
