The process by which oligodendrocytes in the brain and spinal cord and Schwann cells in the peripheral nervous system wrap axons with compact layers of their plasma membrane. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier.

oxidoreductase activity, acting on phosphorus or arsenic in donors

Catalysis of an oxidation-reduction (redox) reaction in which a phosphorus- or arsenic-containing group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.

Any process that modulates the frequency, rate or extent of the metabolic processes by which individual cells transform chemical substances.

The process by which the axon of a neuron is insulated by nerve ensheathment cells.

oxidoreductase activity, acting on phosphorus or arsenic in donors, with disulfide as acceptor

oxidoreductase activity, acting on phosphorus or arsenic in donors, with disulphide as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which a phosphorus- or arsenic-containing group acts as a hydrogen or electron donor and reduces a disulfide.

negative regulation of cellular metabolism

Any process that stops, prevents or reduces the rate of the metabolic processes by which individual cells transform chemical substances.

single-stranded DNA specific endodeoxyribonuclease activity

Catalysis of the hydrolysis of ester linkages within a single-stranded deoxyribonucleic acid molecule by creating internal breaks.

The enzymatic generation of superoxide, the superoxide anion O2- (superoxide free radical), or any compound containing this species, by a cell in response to environmental stress, thereby mediating the activation of various stress-inducible signaling pathways.

oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen

positive regulation of cellular metabolism

Any process that activates or increases the rate of the metabolic processes by which individual cells transform chemical substances.
