Mannosyl_trans

Mannosyl_trans
PFAM accession number:PF05007
Interpro abstract (IPR007704):

PIG-M has a DXD motif. The DXD motif is found in many glycosyltransferases that utilise nucleotide sugars. It is thought that the motif is involved in the binding of a manganese ion that is required for association of the enzymes with nucleotide sugar substrates [ (PUBMED:11226175) ].

GO process:GPI anchor biosynthetic process (GO:0006506)
GO component:integral component of membrane (GO:0016021)
GO function:glycolipid mannosyltransferase activity (GO:0004376), alpha-1,4-mannosyltransferase activity (GO:0051751)
