 In this work glycosyl hydrolase (GH) family 30 (GH30) is analyzed and shown to consist of its currently classified member sequences as well as several homologous sequence groups currently assigned within family GH5. A large scale amino acid sequence alignment and a phylogenetic tree were generated and GH30 groups and subgroups were designated. A partial rearrangement in the GH30 defining side-associated ß-domain contributes to the differentiation of two major groups that contain up to eight subgroups. For this CAZy family of Clan A enzymes the dual domain fold is conserved, suggesting that it may be a requirement for evolved function. This work redefines GH family 30 and serves as a guide for future efforts regarding enzymes classified within this family.
