- * Cytochrome c and c1 heme lyases signatures *
- **********************************************
-
- Cytochrome c heme lyase (CCHL) (EC 4.4.1.17) and cytochrome c1 heme lyase
- (CC1HL) [1] are mitochondrial enzymes that catalyze the covalent attachment of
- a heme group on two cysteine residues of cytochrome c and c1.
-
- These two enzymes are functionally and evolutionary related. As signature
- patterns, we selected two conserved regions: the first is located in the
- central section and the second in the C-terminal section. Both patterns
- contain conserved histidine, tryptophan and acidic residues which could be
- important for the interaction of the enzymes with the apoproteins and/or the
- heme group.
-
- -Consensus pattern: H-N-x(2)-N-E-x(2)-W-[NQ]-x(4)-W-E
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
-
- -Consensus pattern: P-F-D-R-H-D-W
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
