- * Lysyl oxidase putative copper-binding region signature *
- **********************************************************
-
- Lysyl oxidase (EC 1.4.3.13) (LOX) [1] is an extracellular copper-dependent
- enzyme that catalyzes the oxidative deamination of peptidyl lysine residues in
- precursors of various collagens and elastins. The deaminated lysines are then
- able to form aldehyde cross-links.
-
- LOX binds a single copper atom which seems to reside within an octahedral
- coordination complex which includes at least three histidine ligands. Four
- histidine residues are clustered in a central region of the enzyme. This
- region is thought to be involved in cooper-binding and is called the 'copper-
- talon' [1]. We have used this region as a signature pattern.
-
- -Consensus pattern: W-E-W-H-S-C-H-Q-H-Y-H
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
