Sysname
(2E,5S,6E,8E,10E)-1-aminododeca-2,6,8,10-tetraen-5-ol:pyruvate aminotransferase
Reaction(IUBMB)
(2E,5S,6E,8E,10E)-1-aminododeca-2,6,8,10-tetraen-5-ol + pyruvate = (2E,5S,6E,8E,10E)-5-hydroxydodeca-2,6,8,10-tetraenal + L-alanine [RN:
R12343 ]
Reaction(KEGG)
Substrate
(2E,5S,6E,8E,10E)-1-aminododeca-2,6,8,10-tetraen-5-ol [CPD:
C22091 ];
pyruvate [CPD:
C00022 ]
Product
(2E,5S,6E,8E,10E)-5-hydroxydodeca-2,6,8,10-tetraenal [CPD:
C22087 ];
L-alanine [CPD:
C00041 ]
Comment
The enzyme, characterized from the bacterium Streptomyces coelicolor A3(2), participates in the biosynthesis of coelimycin P1, where it catalyses the amination of (2E,5S,6E,8E,10E)-5-hydroxydodeca-2,6,8,10-tetraenal. L-glutamate can also serve as the amino group donor with lower efficiency.
