A protein complex involved in the catalysis of the formation of the modified nucleotide 1-methyladenosine (m1A) in tRNA. In yeast, it is a heterotetramer of two subunits, Gcd10p and Gcd14p, while in bacteria and archaea it is a homotetramer.

A multimeric protein complex involved in the methylation of specific nucleotides in tRNA.

The function of absorbing and responding to electromagnetic radiation with a wavelength of approximately 730nm. The response may involve a change in conformation.

The function of absorbing and responding to electromagnetic radiation with a wavelength of approximately 660nm. The response may involve a change in conformation.

A multisubunit protein complex that binds to centromeric DNA and initiates kinetochore assembly. In yeast, this complex consists of four subunits, namely Ctf13p, Skp1p, Cep3p and Cbf2p.

The chemical reactions and pathways involving ethanolamine (2-aminoethanol), an important water-soluble base of phospholipid (phosphatidylethanolamine).

The chemical reactions and pathways involving ethanolamine (2-aminoethanol) and compounds derived from it.

The chemical reactions and pathways resulting in the breakdown of acetylcholine, the acetic acid ester of the organic base choline.

The chemical reactions and pathways resulting in the breakdown of any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell.

The chemical reactions and pathways involving acetylcholine, the acetic acid ester of the organic base choline. Acetylcholine is a major neurotransmitter and neuromodulator both in the central and peripheral nervous systems. It also acts as a paracrine signal in various non-neural tissues.

The chemical reactions and pathways involving melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.

The chemical reactions and pathways involving pigment, any general or particular coloring matter in living organisms, e.g. melanin.

The chemical reactions and pathways resulting in the formation of melanin from other compounds, including tyrosine.

The chemical reactions and pathways resulting in the formation of melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.

The chemical reactions and pathways involving any of a group of physiologically important biogenic amines that possess a catechol (3,4-dihydroxyphenyl) nucleus and are derivatives of 3,4-dihydroxyphenylethylamine.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of anthocyanins.

Any process that modulates the frequency, rate or extent of chemical reactions and pathways involving anthocyanins.

The chemical reactions and pathways resulting in the formation of dopamine (3,4-dihydroxyphenylethylamine) from L-tyrosine, via the metabolic precursor 3,4-dihydroxy-L-phenylalanine (L-dopa). Dopamine is a catecholamine neurotransmitter and a metabolic precursor of norepinephrine and epinephrine.
