Prenylated
Prenylation (also known as isoprenylation or lipidation) is the addition of hydrophobic molecules to a protein or a biomolecule. It is usually assumed that prenyl groups (3-methylbut-2-en-1-yl) facilitate attachment to cell membranes, similar to lipid anchors like the GPI anchor, though direct evidence of this has not been observed. Prenyl groups (also called isoprenyl groups, having one hydrogen atom more than isoprene) have been shown to be important for protein–protein binding through specialized prenyl-binding domains. Protein prenylation Protein prenylation involves the transfer of either a farnesyl or a geranylgeranyl moiety to C-terminal cysteine(s) of the target protein. There are three enzymes that carry out prenylation in the cell, farnesyl transferase, Caax protease and geranylgeranyl transferase I. Farnesylation is a type of prenylation, a post-translational modification of proteins by which an isoprenyl group is added to a cysteine residue. It is an important pro ...

Pterocarpan
Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes (i.e. 6''H''- enzofuro ,2-chromene skeleton) which can be formed by coupling of the B ring to the 4-one position. 2'-hydroxyisoflavone reductase is the enzyme responsible for the conversion in ''Cicer arietinum'' and glyceollin synthase for the production of glyceollins, phytoalexins in soybean. Known compounds * Bitucarpin A and B, isolated from the aerial parts of Mediterranean plants ''Bituminaria morisiana'' and ''Bituminaria bituminosa'' * Erybraedin A and B, isolated from the stems of ''Erythrina subumbrans'' and C, isolated from the leaves of ''Bituminaria morisiana'' * Erythrabyssin II, erystagallin A, erythrabissin-1, and erycristagallin isolated from the stems of ''Erythrina subumbrans'' * Glycinol, glyceollidin I and II, glyceollins (glyceollin I, II, III and IV), found in the soybean (''Glycin ...

French Bean
Green beans are young, unripe fruits of various cultivars of the common bean ('' Phaseolus vulgaris''), although immature or young pods of the runner bean (''Phaseolus coccineus''), yardlong bean ( ''Vigna unguiculata'' subsp. ''sesquipedalis''), and hyacinth bean (''Lablab purpureus'') are used in a similar way. Green beans are known by many common names, including French beans (), string beans (although most modern varieties are "stringless"), and snap beans or simply "snaps". In the Philippines, they are also known as "Baguio beans" or "" to distinguish them from yardlong beans. They are distinguished from the many other varieties of beans in that green beans are harvested and consumed with their enclosing pods, before the bean seeds inside have fully matured. An analogous practice is the harvest and consumption of unripened pea pods, as is done with snow peas or sugar snap peas. Culinary use As common food in many countries, green beans are sold fresh, canned, and f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
