Gene names
Name:fabI
Ordered Locus Names:aq_1552
OrganismAquifex aeolicus (strain VF5) [Reference proteome] [HAMAP]
Taxonomic identifier224324 [NCBI]
Taxonomic lineageBacteria › Aquificae › Aquificales › Aquificaceae › Aquifex ›

Protein attributes

Sequence length270 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). Involved in the elongation cycle of fatty acid which are used in the lipid metabolism By similarity.

Catalytic activity

Acyl-[acyl-carrier-protein] + NAD+ = trans-2,3-dehydroacyl-[acyl-carrier-protein] + NADH.

Pathway

Lipid metabolism; fatty acid biosynthesis.

Subunit structure

Homotetramer. Ref.2

Sequence similarities

Belongs to the short-chain dehydrogenases/reductases (SDR) family. FabI subfamily.

Sequence caution

The sequence AAC07465.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
