Sysname
ATP:3-hydroxy-4-methylanthranilate adenylyltransferase
Reaction(IUBMB)
ATP + 3-hydroxy-4-methylanthranilate = diphosphate + 3-hydroxy-4-methylanthranilyl-adenylate [RN:
R11554 ]
Reaction(KEGG)
Substrate
ATP [CPD:
C00002 ];
3-hydroxy-4-methylanthranilate [CPD:
C03986 ]
Product
diphosphate [CPD:
C00013 ];
3-hydroxy-4-methylanthranilyl-adenylate
Comment
The enzyme, characterized from the bacteria Streptomyces anulatus and Streptosporangium sibiricum, activates 3-hydroxy-4-methylanthranilate, a precursor of actinomycin antibiotics and the antitumor antibiotic sibiromycin, to an adenylate form, so it can be loaded onto a dedicated aryl-carrier protein.
