Catalysis of the hydrolysis of alpha-glycosidic linkages in oligo- or poly(sialic) acids.

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

The breakdown into simpler components of a cell wall.

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

The chemical reactions involving an antibiotic, a substance produced by or derived from certain fungi, bacteria, and other organisms, that can destroy or inhibit the growth of other microorganisms.

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

A specialized region of connection between two cells including but not limited to gap junctions, desmosomes, and tight junctions, but excluding direct cytoplasmic junctions such as ring canals.

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

A cell junction at which the cytoplasmic face of the plasma membrane is attached to actin filaments.

An adherens junction which connects two cells to each other.

The chemical reactions involving nucleotide-sugars, any nucleotide in which the distal phosphoric residue of a nucleoside 5'-diphosphate is in glycosidic linkage with a monosaccharide or monosaccharide derivative.

A small junction assombled during the cellularization stage of insect embyrogenesis; spot adherens junctions later fuse to form the zonula adherens.
