Catalysis of the reaction: holocytochrome c = apocytochrome c + heme.

Catalysis of the reaction: 2-hydroxybutane-1,2,4-tricarboxylate = but-1-ene-1,2,4-tricarboxylate + H2O.

Synthesis and ordering of the envelope of pronuclei.

The control of the osmotic activity of the fluid in a cell, tissue, organ, or organism.

molting cycle (sensu Protostomia and Nematoda)

The periodic shedding of part or all of a cuticle, which is then replaced by a new cuticle. As in, but not restricted to, the taxon Protostomia (Protostomia, ncbi_taxonomy_id:33317), and the roundworms (Nematoda, ncbi_taxonomy_id:6231).

The breakdown into simpler components of pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues.

Any process preventing the degeneration of the photoreceptor, a specialized cell type that is sensitive to light.

Differentiated cytoplasm associated with a pole (animal, vegetal, anterior, or posterior) of an oocyte, egg or early embryo.

male analia morphogenesis (sensu Endopterygota)

Formation and development of the analia from the genital disc in males. As in, but not restricted to, the Holometabola (Endopterygota, ncbi_taxonomy_id:33392).

female analia morphogenesis (sensu Endopterygota)

Formation and development of the analia from the genital disc in females. As in, but not restricted to, the Holometabola (Endopterygota, ncbi_taxonomy_id:33392).

The process whose specific outcome is the progression of the sex comb over time, from its formation to the mature structure. The sex combs are the male specific chaetae located on the prothoracic tarsal segment of the prothoracic leg.

Providing the environmental signal that initiates the directed movement of a motile cell or organism towards a lower concentration of that signal.

Catalysis of the hydrolysis of nonterminal peptide linkages in oligopeptides or polypeptides; the optimum reaction pH is below 5 due to an aspartic residue involved in the catalytic process.

Catalysis of the hydrolysis of peptide bonds. Specificity similar to, but narrower than, that of pepsin A. Does not cleave the Gln4-His5 bond in the B chain of insulin.
