A synthetic gene specifying a putative 3,4-dihydroxy-2-butanone 4-phosphate synthase of Candida albicans directed the synthesis of a 22.5 kDa peptide in a recombinant Escherichia coli strain. The recombinant protein was purified to apparent homogeneity by two chromatographic steps and was

The lumazine synthase/riboflavin synthase of Bacillus subtilis is a bifunctional enzyme complex catalysing the formation of riboflavin from 5-amino-6-(D-ribitylamino)-2,4(1H,3H)-pyrimidinedione and L-3,4-dihydroxy-2-butanone-4-phosphate via 6,7-dimethyl-8-ribityllumazine. The complex is composed of 3 alpha (riboflavin synthase) subunits and 60 beta (lumazine synthase) subunits and

The lumazine synthase/riboflavin synthase complex of Bacillus subtilis consists of an icosahedral capsid of 60 beta subunits surrounding a core of 3 alpha subunits. The beta subunits catalyze the condensation of 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione with (3S)-3,4-dihydroxy-2-butanone under formation of 6,7-dimethyl-8-ribityllumazine. This intermediate

The xylene ring of riboflavin (vitamin B2 ) is assembled from two molecules of 3,4-dihydroxy-2-butanone 4-phosphate by a mechanistically complex process that is jointly catalyzed by lumazine synthase and riboflavin synthase. In Bacillaceae, these enzymes form a structurally unique complex comprising
