4.1.1.11 additional information requires pyruvate as a covalently bound, catalytically active prosthetic group, pyruvoyl-dependent enzyme, the pyruvoyl group is generated at a specific internal serine residue of the inactive pi-protein with the coincident cleavage of the Gly-Ser bond 649350 4.1.1.11 additional information the ancillary protein PanM (formerly YhhK) is required in vitro and in vivo for cleavage of the L-aspartate-alpha-decarboxylase zymogen 747435 4.1.1.11 additional information the enzyme requires PanZ, an activator involved in the cleavage of ADCE 746859 4.1.1.11 additional information the translated inactive proenzyme, pi-enzyme, self-processes to create its own covalently bound prosthetic group, a pyruvoyl cofactor, mechanism 650998 4.1.1.11 pyridoxal 5'-phosphate - 727784, 749304 4.1.1.11 pyridoxal 5'-phosphate dependent on 748086 4.1.1.11 pyridoxal 5'-phosphate tautomers of the internal aldimine between PLP and enzyme, overview 727622 4.1.1.11 pyridoxal 5'-phosphate the enzyme contains pyridoxal 5'-phosphate 744560 4.1.1.11 pyruvoyl cofactor - 747128 4.1.1.11 pyruvoyl cofactor dependent on 728571, 747497 4.1.1.11 pyruvoyl cofactor dependent on, the enzyme contains a covalently-bound pyruvoyl cofactor 728266 4.1.1.11 pyruvoyl cofactor dependent on. Pathway for the formation of the pyruvoyl-dependent cofactor in ADC: the beta-hydroxyl of Ser25 attacks the carbonyl of the previous amino-acid residue (i) to form an oxyoxazolidine intermediate, which decomposes (ii) to form an ester intermediate. E1cB elimination (iii) forms a N-terminal dehydroalanyl residue which is hydrolysed (iv) to form the pyruvoyl cofactor (the alpha'-chain). The ester intermediate can also be hydrolysed to yield the inactive alpha'-chain 726592 4.1.1.11 pyruvoyl cofactor the enzyme PanD is synthesized as pro-PanD, which undergoes an auto-proteolytic cleavage at residue Ser25 to yield the catalytic pyruvoyl moiety of the enzyme 728327 4.1.1.11 pyruvoyl cofactor the pyruvoyl group is required for catalysis 726617
