DE   cellobionic acid phosphorylase.
CA   4-O-beta-D-glucopyranosyl-D-gluconate + phosphate = D-gluconate + alpha-
CA   D-glucose 1-phosphate.
CC   -!- The enzyme occurs in cellulolytic bacteria and fungi.
CC   -!- It catalyzes the reversible phosphorolysis of cellobionic acid.
CC   -!- In the synthetic direction it produces 4-O-beta-D-glucopyranosyl-D-
CC       glucuronate from alpha-D-glucose 1-phosphate and D-glucuronate with
CC       low activity.
