Chromatin located near the centromere of a chromosome.

The formation from simpler components of aromatic amino acid family, amino acids with aromatic ring (phenylalanine, tyrosine, tryptophan).

The breakdown into simpler components of aromatic amino acid family, amino acids with aromatic ring (phenylalanine, tyrosine, tryptophan).

The chemical reactions involving amino acids of the histidine family.

Heterochromatic regions of the chromosome found at the telomeres of a chromosome in the nucleus.

histidine family amino acid biosynthesis

The formation from simpler components of amino acids of the histidine family.

Any of the regions of heterochromatin that form a reproducible set of dense bands scattered along the euchromatic arms in polytene chromosomes.

The breakdown into simpler components of amino acids of the histidine family.

The chemical reactions involving any amino acid that requires pyruvate for its synthesis, e.g. alanine.

Catalysis of the reaction: RCO-SR' + H2O = RCOOH + HSR'. This reaction is the hydrolysis of a thiolester bond, an ester formed from a carboxylic acid and a thiol (i.e., RCO-SR'), such as that found in acetyl-coenzyme A.

Circular DNA structures that are not part of a chromosome.

The formation from simpler components of any amino acid that requires pyruvate for its synthesis, e.g. alanine.

Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate.

exonuclease activity, active with either ribo- or deoxyribonucleic acids and producing 5'-phosphomonoesters

exonuclease activity, active with either ribo- or deoxyribonucleic acids and producing 5' phosphomonoesters

Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' or 5' end to yield 5' phosphomonoesters.

hydrolase activity, acting on glycosyl bonds

Catalysis of the hydrolysis of any glycosyl bond.

hydrolase activity, hydrolyzing N-glycosyl compounds

Catalysis of the reaction: tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate.
