pfam16863: NtCtMGAM_N (this model, PSSM-Id:293468 is obsolete and has been replaced by 465286)
N-terminal barrel of NtMGAM and CtMGAM, maltase-glucoamylase
NtCtMGAM_N is a beta-barrel-like structure just N-terminal to the catalytic domain of maltase-glucoamylase in eukaryotes. It contributes to the architecture of the substrate-binding site, by donating a loop that comes into close contact with two regions in the catalytic domain thereby creating the site. This family is frequently found at the N-terminus of Glycosyl hydrolase 31, pfam01055.to which it contributes as above.
