Ribulose-phosphate 3-epimerase (EC 5.1.3.1) (also known as pentose-5-phosphate 3-epimerase or PPE) is the enzyme that converts D-ribulose 5-phosphate into D-xylulose 5-phosphate in Calvin's reductive pentose phosphate cycle. In Alcaligenes eutrophus two copies of the gene coding for PPE are known [1], one is chromosomally encoded (cbbEC), the other one is on a plasmid (cbbeP). PPE has been found in a wide range of organisms from all kingdoms of life. The sequence of PPE is highly related to:
- Escherichia coli D-allulose-6-phosphate 3-epimerase (gene alsE).
- Escherichia coli protein sgcE.
All these proteins have from 209 to 241 amino acid residues.
As signature patterns, we selected two conserved regions which are located in respectively in the N-terminal and in the central part of these proteins.
