Catalysis of the endonucleolytic cleavage of RNA to 5'-phosphomonoesters; cleaves multimeric tRNA precursor at the spacer region; also involved in processing of precursor rRNA, hnRNA and early T7-mRNA; also cleaves double-stranded DNA.

Catalysis of the endonucleolytic cleavage of RNA, removing 5' extra nucleotides from tRNA precursor.

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

Catalysis of the sequential hydrolytic removal of 5'-nucleotides from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.

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

The breakdown into simpler components of UDP, uridine (5'-)diphosphate.

The directed movement of L-aspartate, the levorotatory isomer of the anion of aspartic acid, into, out of, within or between cells.

Catalysis of the reaction: L-tryptophan + tetrahydropteridine + O2 = 5-hydroxy-L-tryptophan + dihydrobiopterin + H2O.

The directed movement of L-cystine (also known as dicysteine) into, out of, within or between cells.

The chemical reactions involving DNA, deoxyribonucleic acid, one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides.

Catalysis of the reaction: L-tyrosine + tetrahydrobiopterin + O2 = 3,4-dihydroxy-L-phenylalanine + dihydrobiopterin + H2O.
