Catalysis of the reaction: 5-alpha-cholest-7-en-3-beta-ol = 5-alpha-cholest-8-en-3-beta-ol.

The breakdown into simpler components of phospholipids, any lipid containing phosphoric acid as a mono- or diester.

The formation from simpler components of folic acid and its derivatives.

The breakdown into simpler components of folic acid and its derivatives.

The formation from simpler components of FMN, riboflavin 5'-(dihydrogen phosphate), a coenzyme for a number of oxidative enzymes including NADH dehydrogenase.

Assists in the delivery of metal ions to target proteins or compartments.

The process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes, such as ammonia, nitrate and nitrogen dioxide.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate + chondroitin = adenosine 3',5'-bisphosphate + chondroitin 4'-sulfate.

Assists in the delivery of copper ions to target proteins or compartments.

superoxide dismutase copper chaperone activity

A copper chaperone specifically delivering copper to the Cu-Zn superoxide dismutase.

cyclin-dependent protein kinase 5 activator complex

Activates cyclin-dependent kinase 5; composed of regulatory and catalytic subunits.

cyclin-dependent protein kinase 5 activator activity

cyclin-dependent protein kinase 5 activator, intrinsic catalyst activity

cyclin-dependent protein kinase 5 activator regulator activity

cyclin-dependent protein kinase 5 activator, intrinsic regulator activity

Modulation of the activity of cyclin-dependent protein kinase 5 activator.

cyclin-dependent protein kinase regulator activity

Modulates the activity of a cyclin-dependent protein kinase, enzymes of the protein kinase family that are regulated through association with cyclins and other proteins.

The removal of an internal amino acid sequence (an intein) from a protein during protein maturation; the excision of inteins is precise and the N- and C-terminal exteins are joined by a normal peptide bond. Protein splicing involves 4 nucleophilic displacements by the 3 conserved splice junction residues.
