IPR004199

Source: InterPro

Description

IPR004199 is a Beta galactosidase small chain/ domain 5.

<p>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 [[cite:PUB00016274]].</p>

Subterm of
GO:0009341
Cellular component Beta-galactosidase complex A protein complex that possesses beta-galactosidase activity, i.e. catalyzes the hydrolysis of terminal non-reducing beta-D-galactose residues in beta-D-galactosides. In E. coli, the complex is a homotetramer; dimeric and hexameric beta-galactosidase complexes have been observed in other species.
