Abstract β-Glucan phosphorylases are carbohydrate-active enzymes that catalyze the reversible degradation of β-linked glucose polymers, with outstanding potential for the biocatalytic bottom-up synthesis of β-glucans as major bioactive compounds.

Based on homology search in the amino acid sequences, a chimeric ß-glucosidase with enzyme activity has been prepared by replacing C-terminal region of Thr509-Arg646 from Cellvibrio gilvus with N-terminal region of Arg160-Gly283 from Ruminococcus al

ANALYTICAL BIOCHEMISTRY
Glycoside phosphorylases (GPs) are interesting enzymes for the glycosylation of chemical molecules. They require only a glycosyl phosphate as sugar donor and an acceptor molecule with a free hydroxyl group. Their narrow substrate specificity, however

In order to create novel β-glucosidase constructs, 8 kinds of chimeric β-glucosidases were constructed using overlapping polymerase chain reaction (PCR) based on Cellvibrio gilvus (CG) and Thermotoga maritima (TM) genes. Two kinds of novel chimeric

The amino acid sequences of beta-glucosidases from Cellvibrio gilvus and Agrobacterium tumefaciens show significant similarity in most of the parts. However, the pH/temperature optima and stabilities of the two enzymes are quite different. C. gilvus

Cellobiose phosphorylase was purified from Cellvibrio gilvus cells by the method reported previously with some modifications, and its kinetic properties were studied in detail. The initial velocity of the synthetic reaction was 1.4 times as fast as t

An enzyme component that hydrolyzes pNP-G2 but not CMC has been isolated from a culture broth of Cellvibrio gilvus by a multi-step procedure involving Butyl-Toyopearl, DEAE-Toyopearl, and CM-Toyopearl chromatographies. The purified enzyme gave a sing
