Any process that stops, prevents or reduces the rate of transcription.

Catalysis of the reaction: S-adenosyl-L-methionine + arsenite = S-adenosyl-L-homocysteine + methylarsonate.

A part of the respiratory chain, containing about 10 polypeptide subunits including four redox centers: cytochrome b/b6, cytochrome c1 and an 2Fe-2S cluster. Catalyzes the oxidation of ubiquinol by oxidized cytochrome c1.

The post translational modification of a protein, particularly secretory proteins and proteins targeted for membranes or specific cellular locations.

The generation of a mature peptide hormone by posttranslational processing of a prohormone.

A part of the respiratory chain, containing the 13 polypeptide subunits of cytochrome c oxidase, including cytochrome a and cytochrome a3. Catalyzes the oxidation of reduced cytochrome c by dioxygen (O2).

The rapid expansion of a lymphocyte population by cell division.

regulation of cyclic nucleotide metabolism

Any process that modulates the frequency, rate or extent of cyclic nucleotide metabolism.

The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).

The formation from simpler components of the heparan sulfate proteoglycan, a glycosaminoglycan with repeat unit consisting of alternating (alpha1-

The chemical reactions involving tetrahydrofolate, 5,6,7,8-tetrahydrofolic acid, a folate derivative bearing additional hydrogens on the pterin moiety.

The formation of bone or of a bony substance, or the conversion of fibrous tissue or of cartilage into bone or a bony substance.

heparan sulfate proteoglycan biosynthesis, polysaccharide chain biosynthesis

heparan sulphate proteoglycan biosynthesis, polysaccharide chain biosynthesis

The formation from simpler components of polysaccharide chain component of heparan sulfate proteoglycan.

The uptake of neurotransmitters by presynaptic neurons or glial cells. This process leads to inactivation and recycling of neurotransmitters. It does not occur during cholinergic synaptic transmission. Instead, acetylcholine is enzymatically degraded in the synaptic cleft.
