General Information | Comment | Organism |
---|---|---|
evolution | isozyme MtbCM belongs to the ?AroQ/AroQc family. The family members exhibit sequence similarity only in the N-terminal moiety, and lack a catalytically crucial and conserved arginine residue in helix H1. The proteins contain a catalytic site which is formed within a single protomer and lacks regulatory domain | Mycobacterium tuberculosis |
malfunction | the inhibition of secretory isozyme MtbCM may hinder the supply of nutrients to the organism | Mycobacterium tuberculosis |
metabolism | Mycobacterium tuberculosis chorismate mutase (MtbCM) catalyzes the rearrangement of chorismate to prephenate in the shikimate biosynthetic pathway which forms the essential amino acids, phenylalanine and tyrosine | Mycobacterium tuberculosis |
physiological function | Mycobacterium tuberculosis chorismate mutase (MtbCM) catalyzes the rearrangement of chorismate to prephenate in the shikimate biosynthetic pathway which forms the essential amino acids, phenylalanine and tyrosine. The secretory isozyme MtbCM (encoded by gene Rv1885c) is assumed to play a key role in pathogenesis of tuberculosis. Isozyme MtbCM is independent of regulation | Mycobacterium tuberculosis |
