- ******************************************************
-
- Imidazoleglycerol-phosphate dehydratase (EC 4.2.1.19) is the enzyme that
- catalyzes the seventh step in the biosynthesis of histidine in bacteria, fungi
- and plants. In most organisms it is a monofunctional protein of about 22 to
- 29 Kd. In some bacteria such as Escherichia coli it is the C-terminal domain
- of a bifunctional protein that include a histidinol-phosphatase domain [1].
-
- We developed two signature patterns that each include two consecutive
- histidine residues.
-
- -Consensus pattern: [LIVM]-D-x-H-H-x(2)-E-x(2)-[GCA]-[LIVM]-[AT]-[LIVM]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
-
- -Consensus pattern: G-x-N-x-H-H-x(2)-E-[STAGC]-x-[FY]-K
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
