- * Renal dipeptidase active site *
- *********************************
-
- Renal dipeptidase (rDP) (EC 3.4.13.19), also known as microsomal dipeptidase,
- is a zinc-dependent metalloenzyme which hydrolyzes a wide range of dipeptides.
- It is involved in renal metabolism of glutathione and its conjugates. It is a
- homodimeric disulfide-linked glycoprotein attached to the renal brush border
- microvilli membrane by a GPI-anchor.
-
- A glutamate residue has recently been shown [1] to be important for the
- catalytic activity of rDP. This residue is in the immediate vicinity of a
- histidine which could be involved in binding the zinc ion.
-
- -Consensus pattern: G-V-E-G-G-H-x-I-D
- [E is the active site residue]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: October 1993 / First entry.
