- * Squash family of serine protease inhibitors signature *
- *********************************************************
-
- The squash family of serine protease inhibitor [1] is one of the numerous
- families of serine proteinase inhibitors. The proteins belonging to this
- family are found in the seeds of cucurbitaceae plants (cucumber, squash,
- bitter gourd, etc.). The basic structure of such a type of inhibitor is
- shown in the following schematic representation:

- 'C': conserved cysteine involved in a disulfide bond.
- '#': active site residue.
- '*': position of the pattern.
-
- The pattern we have used to detect this family of proteins spans the major
- part of the sequence and includes five of the six cysteines involved in
- disulfide bonds.
-
- -Consensus pattern: C-P-x(5)-C-x(2)-D-x-D-C-x(3)-C-x-C
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: June 1992 / Pattern and text revised.
