LUMAZINE SYNTHASE FROM MYCOBACTERIUM TUBERCULOSIS BOUND TO 3-(1,3,7-TRIHYDRO-9-D-RIBITYL-2,6,8-PURINETRIONE-7-YL)

Template:ABSTRACT PUBMED 16984393

Function

[RISB_MYCTU] Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2-butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin.[1]
