This entry represents the second beta sandwich domain found in enzymes belonging to the glycosyl hydrolase 127 family [1]. The beta-sandwich domain is somewhat similar to the N-terminal domain of ErbB4 kinase and is involved in formation of a dimer, which is created by a crystallographic 2-fold axis [1].	Domain
