- * Staphylocoagulase repeat signature *
- **************************************
-
- Staphylocoagulase [1,2] is an extracellular protein produced by several
- strains of Staphylococcus aureus and which specifically forms a complex with
- prothrombin. This complex named staphylothrombin can clot fibrinogen without
- any proteolytic cleavage of prothrombin.
-
- The C-terminal of staphylocoagulase consists in the tandem repeat of a domain
- of 27 amino acids. There are from 6 to 8 of these repeats, depending on the
- strain of Staphylococcus aureus. The region containing these repeats is not
- required for the procoagulant activity.
-
- We have derived a signature pattern specific for the 27 residues repeat of
- staphylocoagulase.
-
- -Consensus pattern: A-R-P-x(3)-K-x-S-x-T-N-A-Y-N-V-T-T-x(2)-[DN]-G-x(3)-Y-G
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
