<p>This entry represents a structural motif found in glycoside hydrolase families 38 (<db_xref db="CAZY" dbkey="GH38"/>, e.g. alpha-mannosidase) [<cite idref="PUB00030417"/>] and 57 (<db_xref db="CAZY" dbkey="GH57"/>, e.g. 4-alpha-glucanotransferase, N-terminal) [<cite idref="PUB00014074"/>], as well as in NodB-like polysaccharide deacetylase and in some hypothetical proteins (e.g. TT1467, N-terminal domain). This domain consists of a 7-stranded beta/alpha barrel, although in some families the beta-barrels may be distorted and may vary in the number of strands. </p> Glycoside hydrolase/deacetylase, beta/alpha-barrel
