Activities in Family	endo-β-1,4-mannanase (EC 3.2.1.78);
Mechanism	inverting
3D Structure Status	lysozyme fold
Note	Created after the work by Shimizu and collaborators. J. Biol. Chem. (2015). [ PMID:26385921 ]. Presents an inverting mechanism in what is a unique feature compared to all other b-mannanases [see Jin et al. ACS Cent. Sci (2016) doi:10.1021/acscentsci.6b00232 ]
