HB HfsE glycosyltransferase

The HfsE gene encodes a 518 amino acid protein in Hirschia baltica, identified as a putative integral membrane glycotransferase. The primary role of this protein is to transfer a glucose-1-phosphate from uridine diphosphate glucose (UDP-glucose) or to an undecaprenyl phosphate (UP), which is a crucial lipid carrier that facilitates the transfer of cell wall intermediates across the cytoplasmic membrane in bacteria. This reaction represents the first step in the synthesis of the holdfast polysaccharide repeat units in the cytoplasm. [1].
