UniProtKB - Q73Q47 (FABV_TREDE)
Protein
Trans-2-enoyl-CoA reductase [NADH]
Gene
fabV
Organism
Treponema denticola (strain ATCC 35405 / DSM 14222 / CIP 103919 / JCM 8153 / KCTC 15104)
Status
Functioni
Involved in the fatty acid synthesis (FAS II). Catalyzes the reduction of the carbon-carbon double bond of crotonyl-CoA to yield butyryl-CoA. In vitro it can also use hexenoyl-CoA and dodecenoyl-CoA as substrates (PubMed:22906002).
3 PublicationsMiscellaneous
Possesses high activity for the reduction reaction, but no activity for the reverse oxidation reaction.1 Publication

Kineticsi
kcat is 385.9 sec(-1) for reductase activity (at pH 6.2 and 25 degrees Celsius) (PubMed:23050861). kcat is 112 sec(-1) for reductase activity with hexenoyl-CoA as substrate (PubMed:22906002). kcat is 91 sec(-1) for reductase activity with crotonyl-CoA as substrate (PubMed:22906002). kcat is 90 sec(-1) for reductase activity with dodecenoyl-CoA as substrate (PubMed:22906002).2 Publications

Pathology & Biotechi
Biotechnological usei
Used in the biosynthesis of medium-chain volatile alcohols as biofuels engineered by microorganisms. The switch from the native flavin-dependent enoyl-CoA reductase used in the production of n-butanol, a key second-generation biofuel, to a flavin-independent trans-enoyl-CoA reductase from T.denticola leads to an order of magnitude increase in product yield in engineered E.coli.1 Publication

Mutagenesisi | 276 | L → A: Significant decrease of the catalytic efficiency; when associated with A-277. The catalytic efficiency is slightly reduces and the affinity is relatively similar to wild-type; when associated with A-277 and A-295. 1 Publication | 1 | |
Mutagenesisi | 277 | V → A: Significant decrease of the catalytic efficiency; when associated with A-276. The catalytic efficiency is slightly reduces and the affinity is relatively similar to wild-type; when associated with A-276 and A-295. 1 Publication | 1 | |
Mutagenesisi | 287 | I → A: Shows 7-, 13- and 15-fold decrease of catalytic efficiency of the reductase activity for hexenoyl-CoA, crotonyl-CoA and dodecenoyl-CoA, respectively. The affinity is relatively similar to wild-type. This mutation may increase the accessibility of the longer acyl chain to the active site pocket. 1 Publication | 1 | |
