The modification of a protein amino acid by phosphopantetheinylation.

Addition of a methyl group to any residue of peptidyl-arginine.

Catalysis of the reaction: phosphoenolpyruvate + N-acetyl-D-mannosamine + H2O = phosphate + N-acetylneuraminate .

two-component signal transduction system (phosphorelay)

A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins.

MAPKKK cascade during osmolarity sensing

MAPKKK cascade involved in signal transduction in response to change in osmotic conditions.

The formation from simpler components of tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid.

protein phosphatase type 1, intrinsic catalyst activity

Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. An ATP, magnesium-dependent protein serine/threonine phosphatase (AMD phosphatase) that consists of a catalytic subunit of 38 kDa and a modulator subunit of 23 kDa, which is subject to phosphorylation, thus activating the phosphatase.

Catalysis of the reaction: 2 cob(I)alamin + NAD+ = 2 cob(II)alamin + NADH + H+.

Cascade of at least three protein kinase activities culminating in the phosphorylation and activation of a MAP kinase. MAPKKK cascades lie downstream of numerous signaling pathways.
