RPSBLAST alignment for GI: 254781100 and conserved domain: cd06853

>gnl|CDD|133463 cd06853, GT_WecA_like, This subfamily contains Escherichia coli WecA, Bacillus subtilis TagO and related proteins. WecA is an UDP-N-acetylglucosamine (GlcNAc):undecaprenyl-phosphate (Und-P) GlcNAc-1-phosphate transferase that catalyzes the formation of a phosphodiester bond between a membrane-associated undecaprenyl-phosphate molecule and N-acetylglucosamine 1-phosphate, which is usually donated by a soluble UDP-N-acetylglucosamine precursor. WecA participates in the biosynthesis of O antigen LPS in many enteric bacteria and is also involved in the biosynthesis of enterobacterial common antigen. A conserved short sequence motif and a conserved arginine at a cytosolic loop of this integral membrane protein were shown to be critical in recognition of substrate UDP-N-acetylglucosamine.
