Short name: B-gal_small/dom_5

Domain relationships

Description

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, which is comprised of five domains, where it represents domain 5. It contains an N-terminal loop that swings towards the active site upon the deep binding of a ligand to produce a closed conformation [PMID: 11732897].
