Catalysis of the hydrolysis of peptide bonds. Similar to cathepsin D, but slightly broader specificity.

Catalysis of the hydrolysis of peptide bonds. Preferential cleavage: hydrophobic, preferably aromatic, residues in P1 and P1' positions. Cleaves Phe1-Val2, Gln4-His5, Glu13-Ala14, Ala14-Leu15, Leu15-Tyr16, Tyr16-Leu17, Gly23-Phe24, Phe24-Phe25 and Phe25-Tyr26 bonds in the B chain of insulin.

Catalysis of the cleavage of Leu-Xaa bond in angiotensinogen to generate angiotensin I.

Catalysis of the degradation of gelatin; little activity on hemoglobin. Specificity on B chain of insulin more restricted than pepsin A; does not cleave Phe1-Val2, Gln4-His5 or Gly23-Phe24.

Any process that modulates the extent to which the two centrioles within a centrosome remain tightly paired; may be mediated by the assembly and disassembly of a proteinaceous linker.

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

Catalysis of the preferential cleavage of Tyr-Xaa, Met-Xaa or Arg-Xaa with Leu or Val as the P2 residue.

The chemical reactions involving nitrobenzene (nitrobenzol), a derivative of benzene with an NO2 group attached to the ring. It is a yellow aromatic liquid used in perfumery and manufactured in large quantities in the preparation of aniline.

Catalysis of the conversion of isotrichodermol to isotrichodermin.

The process whose specific outcome is the progression of the R8 photoreceptor over time, from its formation to the mature structure. The R8 photoreceptor is the founding receptor of each ommatidium.

Process by which a cell becomes capable of differentiating autonomously into an R8 cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed.

The process whereby a relatively unspecialized cell acquires the specialized features of the R8 photoreceptor.

The process whereby a relatively unspecialized cell acquires the specialized features of the R7 photoreceptor.
