Cofactorⁱ

Mn²⁺1 PublicationNote: Mn²⁺ is the most effective activator, followed by Co²⁺, Ca²⁺, Mg²⁺ and Ni²⁺.1 Publication

Activity regulationⁱ

Regulated by the end-product isoleucine via a feedback inhibition. The binding of isoleucine has inhibitory effects on the binding of both pyruvate and acetyl-CoA. May act via conformational change of the dimer interface of the regulatory domain, leading to inhibition of the catalytic reaction.1 Publication

Kineticsⁱ

kcat is 2.41 sec(-1) (PubMed:15292141). kcat is 10.3 sec(-1) with acetyl-CoA as substrate (PubMed:18498255). kcat is 9.13 sec(-1) with pyruvate as substrate (PubMed:18498255).2 Publications

Temperature dependenceⁱ

Optimum temperature is 35-40 degrees Celsius.1 Publication

Pathwayⁱ: L-isoleucine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 2-oxobutanoate from pyruvate.1 Publication This subpathway is part of the pathway L-isoleucine biosynthesis, which is itself part of Amino-acid biosynthesis.

Domainⁱ

Contains a catalytic N-terminal domain and a C-terminal regulatory domain, linked together by a flexible region (PubMed:18498255, PubMed:19351325). The catalytic domain consists of a TIM barrel flanked by an extended C-terminal region. The active site is located at the center of the TIM barrel near the C-terminal ends of the beta-strands and is composed of conserved residues of the beta-strands of one subunit and the C-terminal region of the other (PubMed:18498255).2 Publications
