>TIGR01208 rmlA_long glucose-1-phosphate thymidylyltransferase; InterPro: IPR005908 Synonym: dTDP-D-glucose synthase This group of proteins comprises a tightly conserved but broadly distributed subfamily of known and putative bacterial glucose-1-phosphate thymidylyltransferases (2.7.7.24 from EC). It is well characterised in several species as the first of four enzymes involved in the biosynthesis of dTDP-L-rhamnose, a cell wall constituent and a feedback inhibitor of the enzyme. dTTP + alpha-D-glucose 1-phosphate = diphosphate + dTDP-glucose The family of known and putative glucose-1-phosphate thymidyltransferases shows a deep split into a short form (see IPR005907 from INTERPRO) and a long form described by this model. The homotetrameric short form is found in numerous bacterial species that incorporate dTDP-L-rhamnose, which it helps synthesize, into the cell wall. It is subject to feedback inhibition. The long form, in contrast, is found in many species for which it serves as a sugar-activating enzyme for antibiotic biosynthesis and or other, unknown pathways, and in which dTDP-L-rhamnose is not necessarily produced. .
