Alpha-isopropylmalate/homocitrate synthase, conserved site

InterPro entry
Short nameAIPM/Hcit_synth_CS

Description

A number of enzymes have been shown to be functionally as well as evolutionary related
[1]
. The nifV and leuA genes encode homocitrate synthase and alpha-isopropylmalate synthase, respectively The N-terminal parts of NifV and LeuA from bacteria are highly similar to each other
[2]
. Homocitrate synthase (
2.3.3.14
) (gene nifV) is involved in the biosynthesis of the iron-molybdenum cofactor of nitrogenase and catalyzes the condensation of acetyl-CoA and alpha-ketoglutarate into homocitrate. Alpha-isopropylmalate synthase (
2.3.3.13
) catalyses the first step in the biosynthesis of leucine, the condensation ofacetyl-CoA and alpha-ketoisovalerate to form 2-isopropylmalate synthase.
