Names

Accepted name:
meprin B
Other name:
meprin-b
Systematic name:

Reaction

Cofactor

Comments:

A brush border membrane-bound metalloendopeptidase known from the intestine of all mouse strains that have been tested, and the kidney of certain inbred strains. A tetramer of meprin b subunits (in contrast to meprin A, which contains both a and b subunits). Occurs in the kidney as a proenzyme that can be activated by trypsin. Meprin B is inhibited by both EDTA and 1,10-phenanthroline, but not by phosphoramidon, captopril or thiorphan. In peptidase family M12 (astacin family).
