Catalysis of the endonucleolytic cleavage of DNA to 3'-phosphodinucleotide and 3'-phosphooligonucleotide end products.

Catalysis of the sequential cleavage of mononucleotides from a free 5' or 3' terminus of an RNA molecule.

The directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of, within or between cells.

Catalysis of the exonucleolytic cleavage of poly(A) to 5'-AMP.

Catalysis of the hydrolysis of ester linkages within deoxyribonucleic acid.

The directed movement of amines, including polyamines, organic compounds containing one or more amino groups, into, out of, within or between cells.

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.

The chemical reactions involving a pyrimidine nucleotide, a compound consisting of nucleoside (a pyrimidine base linked to a deoxyribose or ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety.

MAPKKK cascade during osmolarity sensing

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

The formation from simpler components of a pyrimidine nucleotide, a compound consisting of nucleoside (a pyrimidine base linked to a deoxyribose or ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety.

The formation from simpler components of UMP, uridine monophosphate.

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.
