Apparent second order rate constant of chorismate mutase

Range ~10^6 M^-1×sec^-1
Organism Bacteria Bacillus subtilis
Reference Mattei P, Kast P, Hilvert D. Bacillus subtilis chorismate mutase is partially diffusion-controlled. Eur J Biochem. 1999 Apr261(1):25-32. p.26 left column top paragraphPubMed ID10103029
Comments "...the apparent second order rate constant kcat/Km (~10^6M^-1×sec^-1) is substantially smaller than the rate constant generally associated with the diffusion of small molecules (~10^8-10^9M^-1×sec^-1[27,28])."
