Binding Site | |
Calcium Binding | |
catalytic Activity | CATALYTIC ACTIVITY: Reaction=Cleavage of the proline- and hydroxyproline-rich proteins of the Chlamydomonas cell wall. Also cleaves azocasein, gelatin and Leu-Trp-Met-|-Arg-Phe-Ala.; EC=3.4.24.38; |
DNA Binding | |
EC Number | 3.4.24.38 |
Enzyme Function | FUNCTION: Mediates digestion of the cell walls of the 2 mating type gametes during mating as a necessary prelude to cell fusion. This enzyme acts specifically on the framework proteins (inner wall) of the cell wall, cleaving several model peptides at specific sites. |

Interact With | |
Induction | INDUCTION: By the signal of flagellar agglutination between gametes of the opposite mating type. |
Subcellular Location | SUBCELLULAR LOCATION: Periplasm. Secreted, cell wall. Note=Stored in the periplasm of gametes until its release. Secreted concurrently with release of the cell walls. |
Modified Residue | |
Post Translational Modification | PTM: Present in 2 forms: an inactive V-form in vegetative cells and an active and soluble G-form. The V-form enzyme may be converted to the G-form enzyme during gametic differentiation under nitrogen-starved conditions. |
