Catalysis of the reaction: D-ribose = D-ribulose.

The secretion of milk by the mammary gland.

The sequential process by which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers.

Catalysis of the reaction: an N-D-ribosylpyrimidine + H2O = D-ribose + a pyrimidine.

The stopping of bleeding (loss of body fluid) or the arrest of the circulation to an organ or part.

Catalysis of the reaction: ATP + rhodopsin = ADP + phosphorhodopsin.

The change in form (cell shape and size) that occurs during sexual reproduction in order to facilitate direct contact between the compatible mating types.

syncytium formation by plasma membrane fusion

The formation of a syncytium, a mass of cytoplasm containing several nuclei enclosed within a single plasma membrane, by the fusion of the plasma membranes of two or more individual cells.

regulation of polarized epithelial cell differentiation

Any process that modulates the frequency, rate or extent of polarized epithelial cell differentiation.

Catalysis of the reaction: acetyl-CoA + an arylamine = CoA + an N-acetylarylamine.

pheromone-dependent signal transduction during conjugation with cellular fusion

transduction of mating signal (sensu Fungi)

The processes involving the relay, amplification or dampening of a signal generated in response to pheromone exposure in organisms that undergo conjugation with cellular fusion.

Catalysis of the reaction: N-formyl-L-kynurenine + H2O = formate + L-kynurenine.

cell cycle arrest in response to pheromone

The processes that lead to a halt in cell cycle progression (cessation of cell cycle transitions) as a result of a pheromone stimulus.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate + a phenol = adenosine 3',5'-bisphosphate + an aryl sulfate.
