Organization of the galactose and lactose genes in the S. pluranimium TH11417. a Comparison of structures and indentity of S. pluranimium (CP025536), and S. mutans (AE014133) and S. agalactiae (HF952105) lac locus genes. The directions of genes are indicated by arrows. Percent identities of amino-acid sequences are indicated. b Comparison of structures and indentity of S. pluranimium (CP025536), and S. mutans (AE014133) and S. salivarius (CP015283) gal locus genes. The genes code for the following proteins: lacR, the DeoR-like negative transcriptional regulator; lacA and lacB, the A and B subunits of the galactose-6-phosphate isomerase; lacC, the tagatose-6-phosphate kinase; lacD, tagatose-1,6-bisphosphate aldolase; lacF and lacE, the A and BC components of the lactose-PTS enzyme II; and lacG, the 6-phospho-β-galactosidase; lacS, lactose permease; lacZ, β-galactosidase; galR, putative transcriptional regulator; galK, galactokinase; galT, galactose-1-phosphate uridylyltransferase; galE, UDP-glucose 4-epimerase; galM, galactose mutarotase
