Enables the directed movement of pyrimidines, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, into, out of, within or between cells.

Catalysis of the reaction: sugar(out) + H+(out) = sugar(in) + H+(in).

protein kinase CK2, intrinsic catalyst activity

Catalysis of the reaction: casein + ATP = phosphocasein + ADP.

Enables the directed movement of fructose into, out of, within or between cells. Fructose exists in a open chain form or as a ring compound. D-fructose is the sweetest of the sugars and is found free in a large number of fruits and honey.

calmodulin regulated protein kinase activity

calmodulin-dependent protein kinase I activity

Catalysis of the reaction: ATP + protein = ADP + O-phosphoprotein.

Enables the directed movement of the hexose monosaccharide glucose into, out of, within or between cells.

calcium- and calmodulin-dependent protein kinase activity

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.
