HHsearch alignment for GI: 254780479 and conserved domain: cd03430

>cd03430 GDPMH GDP-mannose glycosyl hydrolase (AKA GDP-mannose mannosyl hydrolase (GDPMH)) is a member of the Nudix hydrolase superfamily. This class of enzymes is unique from other members of the superfamily in two aspects. First, it contains a modified Nudix signature sequence. The slight changes to the conserved sequence motif, GX5EX7REUXEEXGU, where U = I, L or V), are believed to contribute to the removal of all magnesium binding sites but one, retaining only the metal site that coordinates the pyrophosphate of the substrate. Secondly, it is not a pyrophosphatase that substitutes at a phosphorus; instead, it hydrolyzes nucleotide sugars such as GDP-mannose to GDP and mannose, cleaving the phosphoglycosyl bond by substituting at a carbon position. GDP-mannose provides mannosyl components for cell wall synthesis and is required for the synthesis of other glycosyl donors (such as GDP-fucose and colitose) for the cell wall. The importance of GDP-sugar hydrolase activities is thus close
