Putative glucose-1-phosphate thymidylyltransferase, C-terminal Left-handed parallel beta-Helix (LbH) domain: Proteins in this family show simlarity to glucose-1-phosphate adenylyltransferases in that they contain N-terminal catalytic domains that resemble a dinucleotide-binding Rossmann fold and C-terminal LbH fold domains. Members in this family are predicted to be glucose-1-phosphate thymidylyltransferases, which are involved in the dTDP-L-rhamnose biosynthetic pathway. Glucose-1-phosphate thymidylyltransferase catalyzes the synthesis of deoxy-thymidine di-phosphate (dTDP)-L-rhamnose, an important component of the cell wall of many microorganisms. The C-terminal LbH domain contains multiple turns, each containing three imperfect tandem repeats of a hexapeptide repeat motif (X-[STAV]-X-[LIV]-[GAED]-X). Proteins containing hexapeptide repeats are often enzymes showing acyltransferase activity.
