- * Acylphosphatase signatures *
- ******************************
-
- Acylphosphatase (EC 3.6.1.7) [1,2] catalyzes the hydrolysis of various acyl
- phosphate carboxyl-phosphate bonds such as carbamyl phosphate, succinyl
- phosphate, 1,3-diphosphoglycerate, etc. The physiological role of this enzyme
- is not yet clear. Acylphosphatase is a small protein of around 100 amino-acid
- residues. There are two known isozymes. One seems to be specific to muscular
- tissues, the other, called 'organ-common type', is found in many different
- tissues.
-
- More than 50% of the positions in the acylphosphatase sequences are conserved.
- As signature patterns, we selected two conserved regions. The first is located
- in the N-terminal section, while the second is found in the central part of
- the protein sequence.
-
- -Consensus pattern: S-V-D-Y-E-[LIVM]-x-G-[RKT]

- -Other sequence(s) detected in SWISS-PROT: NONE.
-
- -Consensus pattern: G-T-V-x-G-Q-x-Q-G-P
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
