Chains Accession Name Description Comments Source PF02836 Glycosyl hydrolases family 2, TIM barrel domain (Glyco_hydro_2_C) Glycosyl hydrolases family 2, TIM barrel domain This family contains beta-galactosidase, beta-mannosidase and beta-glucuronidase activities. Domain PF02837 Glycosyl hydrolases family 2, sugar binding domain (Glyco_hydro_2_N) Glycosyl hydrolases family 2, sugar binding domain This family contains beta-galactosidase, beta-mannosidase and beta-glucuronidase activities and has a jelly-roll fold. The domain binds the sugar moiety during the sugar-hydrolysis reaction. Domain PF16353 Beta-galactosidase, domain 4 (LacZ_4) Beta-galactosidase, domain 4 This entry represents domain 4 found in beta-galactosidase [1] and it is organised in a jelly-roll type barrel (Rutkiewicz-Krotewicz M. et al. Crystals 2018, 8(1), 13, https://doi.org/10.3390/cryst8010013). Domain PF02929 Beta galactosidase small chain (Bgal_small_N) Beta galactosidase small chain This domain comprises the small chain of dimeric beta-galactosidases EC:3.2.1.23. This domain is also found in single chain beta-galactosidase. Domain
