Terpene Synthase N Terminal Domain
In molecular biology, this protein domain belongs to the terpene synthase family (TPS). Its role is to synthesize terpenes, which are part of primary metabolism, such as sterols and carotene, and also part of the secondary metabolism. This entry will focus on the N terminal domain of the TPS protein. Function Terpenes synthases have a role in producing important molecules in metabolism, these molecules are part of a large group called terpenoids . In particular, the N terminal domain has feature of the copalyl diphosphate synthase (CPS) active site. Structure The N-terminal domain forms an alpha-barrel similar to that of the sesquiterpene cyclase epiaristolochene synthase. Conservation Sequences containing this protein domain belong to the terpene synthase family. It has been suggested that this gene family be designated tps (for terpene synthase). Sequence comparisons reveal similarities between the monoterpene (C10) synthases, sesquiterpene (C15) synthases and the diterpe ...

Terpene Synthase C Terminal Domain
In molecular biology, this protein domain belongs to the terpene synthase family (TPS). Its role is to synthesize terpenes, which are part of primary metabolism, such as sterols and carotene, and also part of the secondary metabolism. This entry will focus on the C terminal domain of the TPS protein. Function Terpenes synthases have a role in producing important molecules in metabolism, these molecules are part of a large group called terpenoids . In particular, the C terminal domain catalyzes the cyclization of geranyl diphosphate, orienting and stabilizing multiple reactive carbocation intermediates. Or in simpler terms, the C terminal aids the synthesis of new molecules. Structure It is thought to have at least two alpha helices. Conservation Sequences containing this protein domain belong to the terpene synthase family. It has been suggested that this gene family be designated tps (for terpene synthase). Sequence comparisons reveal similarities between the monoterpene (C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terpenes And Terpenoids
Terpenes () are a class of natural products consisting of compounds with the formula (C5H8)n for n > 1. Comprising more than 30,000 compounds, these unsaturated hydrocarbons are produced predominantly by plants, particularly conifers. Terpenes are further classified by the number of carbons: monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), as examples. The terpene alpha-pinene, is a major component of the common solvent, turpentine. History and terminology The term ''terpene'' was coined in 1866 by the German chemist August Kekulé to denote all hydrocarbons having the empirical formula C10H16, of which camphene was one. Previously, many hydrocarbons having the empirical formula C10H16 had been called "camphene", but many other hydrocarbons of the same composition had had different names. Kekulé coined the term "terpene" in order to reduce the confusion. The name "terpene" is a shortened form of "terpentine", an obsolete spelling of "turpentine". Although sometimes u ...
