Catalysis of the removal of terminal peptide residues that are substituted, cyclized or linked by isopeptide bonds (peptide linkages other than those of a-carboxyl to a-amino groups).

Catalysis of the specific cleavage of an Arg-Val bond in plasminogen to form plasmin.

mating-type factor pheromone receptor activity

Combining with a mating-type factor pheromone to initiate a change in cell activity.

mating-type a-factor pheromone receptor activity

Combining with the mating-type a-factor pheromone to initiate a change in cell activity.

mating-type alpha-factor pheromone receptor activity

Combining with the mating-type alpha-factor pheromone to initiate a change in cell activity.

An enzyme complex composed of two catalytic subunits, alpha1 and alpha2, which form a catalytic dimer, and a non-catalytic, regulatory subunit, beta. Modulates the action of platelet-activating factor (PAF).

A heterodimeric complex containing the products of the insect genes Ecdysone receptor (EcR) and ultraspiracle (usp). Binding of ecdysone promotes association between the two subunits, and the receptor complex then initiates molting and metamorphosis by binding DNA and regulating the transcription of target genes.

Catalysis of the hydrolysis of peptide bonds.

Catalysis of the hydrolysis of peptide linkages in oligopeptides or polypeptides; a cysteine residue is at the active center.

The action of a molecule that contributes to the structural integrity of a cuticle.

Catalysis of the hydrolysis of terminal peptide linkages in oligopeptides or polypeptides. Enzymes of this class contain a chelated metal ion essential to their catalytic activity at their active sites.

The periodic casting off and regeneration of an outer covering of cuticle, feathers, hair, horns, skin, etc.

Catalysis of the hydrolysis of peptide linkages in oligopeptides or polypeptides; a serine residue (and a histidine residue) are at the active center.

Any process that modulates the frequency, rate or extent of the formation from simpler components of fatty acids, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils.
