Identification of enzymatic functions of osmo-regulated periplasmic glucan biosynthesis proteins from Escherichia coli reveals a novel glycoside hydrolase family.
-
E. coli OpgG has beta-1,2-glucanase activity and belongs to the newly defined GH186 family, providing the primary biochemical basis for ISS transfer to P. putida OpgG.
"EcOpgG was found to hydrolyze β-1,2-glucans; however, the catalytic velocity was very low"
Linear osmoregulated periplasmic glucans are encoded by the opgGH locus of Pseudomonas aeruginosa.
-
Closely related Pseudomonas opgGH produces linear beta-1,2-linked OPGs, supporting the pathway context for P. putida opgG/opgH.
"PA14 is involved in the synthesis of linear polymers with beta-1,2-linked"
Structural analysis of Escherichia coli OpgG, a protein required for the biosynthesis of osmoregulated periplasmic glucans.
-
The E. coli OpgG structure contains a carbohydrate-related beta-sandwich domain with an aromatic/acidic cleft, supporting catalytic-family context.
"It exhibits a large cleft comprising many aromatic and acidic"
OpenScientist gene research for opgG
-
OpenScientist supports OpgG as a periplasmic GH186 beta-1,2-glucanase inferred from characterized orthologs, sequence conservation, and operon context.
