Catalysis of the reaction: ATP + (myosin-light-chain) = ADP + (myosin-light-chain) phosphate.

Interacting selectively with a kinase, any enzyme that catalyzes the transfer of a phosphate group.

Interacting selectively with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate.

phosphorylase kinase, intrinsic catalyst activity

Catalysis of the reaction: 4 ATP + 2 phosphorylase B = 4 ADP + phosphorylase A.

Interacting selectively with any phosphatase.

Interacting selectively with any protein phosphatase.

Interacting selectively with a specific domain of a protein.

Interacting selectively with a syntaxin, a SNAP receptor involved in the docking of synaptic vesicles at the presynaptic zone of a synapse.

Enables the directed movement of iron (Fe) ions into, out of, within or between cells.

Catalysis of the reaction: S-adenosyl-L-methionine + protein C-terminal S-farnesyl-L-cysteine = S-adenosyl-L-homocysteine + protein C-terminal S-farnesyl-L-cysteine methyl ester.

Catalysis of the transfer of a phosphate group, usually from ATP, to a protein substrate.

Catalysis of the reaction: ATP + protein L-histidine = ADP + protein phospho-L-histidine.

Catalysis of the reaction: ATP + a protein serine/threonine = ADP + protein serine/threonine phosphate.

Enables the directed movement of zinc (Zn) ions into, out of, within or between cells.

transmembrane receptor protein serine/threonine kinase activity

Catalysis of the transfer of a specific substance or related group of substances from one side of the membrane to the other.

Enables the directed movement of mannose into, out of, within or between cells. Mannose is the aldohexose manno-hexose, the C-2 epimer of glucose. The D-(+)-form is widely distributed in mannans and hemicelluloses and is of major importance in the core oligosaccharide of N-linked oligosaccharides of glycoproteins.

Catalysis of the reaction: ATP + H2O + Ca2+(cis) = ADP + phosphate + Ca2+(trans).

The chemical reactions involving folic acid and its derivatives.
