the pathogen Brucella spp. expresses two proteins that exhibit lumazine synthase activity, RibH1 and RibH2. RibH1 appears to be the functional lumazine synthase in Brucella spp., whereas RibH2, an enzyme of lower catalytic activity, is a virulence factor presumably acting in response to oxidative stress

an early optical transient absorbing around 330 nm is interpreted as a Schiff base intermediate obtained by reaction of the position 5 amino group of the heterocyclic substrate with the carbonyl group of 3,4-dihydroxy-2-butanone 4-phosphate. A second transient with an absorption maximum at 445 nm represents an intermediate resulting from the elimination of phosphate from the Schiff base. The rate-determining step is the subsequent formation of the 7-exomethylene type anion of 6,7-dimethyl-8-ribityllumazine

the pathogen Brucella spp. expresses two proteins that exhibit lumazine synthase activity, RibH1 and RibH2. RibH1 appears to be the functional lumazine synthase in Brucella spp., whereas RibH2, an enzyme of lower catalytic activity, is a virulence factor presumably acting in response to oxidative stress
