Substrate specificities
The two known members of glycoside hydrolase family 82 enzymes cleave the β-1,4 galactosidic bond of the marine algal polysaccharide iota-carrageenan [1] yielding products of the neocarrabiose series.
Kinetics and Mechanism
Family 82 enzymes are inverting enzymes, as first shown by NMR [1] on the iota-carrageenase from Alteromonas fortis.
Catalytic Residues
Three-dimensional structures
Family Firsts
- First sterochemistry determination
- GH82 enzymes are inverting as shown by NMR [1].
- First general acid residue identification
- First general base residue identification
- First 3-D structure
iota-carrageenase from Alteromonas fortis [2]. The structure belongs to the β-helix fold (PDB 1h80 and PDB 1ktw).
