- * Adenosine and AMP deaminase signature *
- *****************************************
-
- Adenosine deaminase (EC 3.5.4.4) catalyzes the hydrolytic deamination of
- adenosine into inosine. AMP deaminase (EC 3.5.4.6) catalyzes the hydrolytic
- deamination of AMP into IMP. It has been shown [1] that these two types of
- enzymes share three regions of sequence similarities; these regions are
- centered on residues which are proposed to play an important role in the
- catalytic mechanism of these two enzymes. We have selected one of these
- regions, it contains two conserved aspartic acid residues that are potential
- active site residues.
-
- -Consensus pattern: S-[LIVM]-[NS]-T-D-D-P
- [The two D's are putative active site residues]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: December 1991 / Pattern and text revised.
