Catalysis of the reaction: 2,3-dihydroxy-3-methylbutanoate = 3-methyl-2-oxobutanoate + H2O.

Catalysis of the reaction: dimethylallyl diphosphate + isopentenyl diphosphate = diphosphate + geranyl diphosphate.

Catalysis of the removal of a methyl group from N-nitrosodimethylamine.

Catalysis of the removal of a methyl group from a substrate.

Catalysis of the reaction: (R)-5-diphosphomevalonate + ATP = ADP + CO(2) + H(+) + isopentenyl diphosphate + phosphate.

Catalysis of the reaction: S-adenosyl-L-methionine + 2-(3-carboxy-3-aminopropyl)-L-histidine = S-adenosyl-L-homocysteine + 2-(3-carboxy-3-(methylammonio)propyl)-L-histidine.

Catalysis of the reactions: a (3Z)-enoyl-CoA = a 4-saturated (2E)-enoyl-CoA or a (3E)-enoyl-CoA = a 4-saturated (2E)-enoyl-CoA.

Catalysis of the reaction: UDP-N-acetyl-D-glucosamine + dolichyl phosphate = UDP + dolichyl N-acetyl-alpha-D-glucosaminyl phosphate.

Catalysis of the reaction: L-dopachrome = 5,6-dihydroxyindole-2-carboxylate.

Catalysis of the reaction: CTP + dolichol = CDP + dolichyl phosphate.

Catalysis of the repair of T/G mismatches arising from deamination of 5-methylcytosine in DNA by nicking double-stranded DNA within the sequence CT(AT)GN or NT(AT)GG next to the mismatched thymidine residue. The incision is mismatch-dependent and strand-specific, in favor of the G-containing strand. The incision serves as a starting point for subsequent excision repair by DNA polymerase I, which excises thymidine and reinserts cytidine.

Catalysis of the reaction: dolichyl phosphate D-mannose + protein = dolichyl phosphate + O-D-mannosylprotein.

Catalysis of the reaction: O-phospho-L-seryl-tRNACys + sulfide = L-cysteinyl-tRNACys + phosphate.

Catalysis of the reaction: ATP + L-pyrrolysine + tRNA(Pyl) = AMP + diphosphate + L-pyrrolysyl-tRNA(Pyl).

Catalysis of the reaction: S-(5-deoxy-D-ribos-5-yl)-L-homocysteine = (S)-4,5-dihydroxypentane-2,3-dione + L-homocysteine.

A complex composed of four polypeptides, a telomere-protecting terminal protein (Tpg), a telomere-associated protein (Tap), DNA polymerase (PolA) and topoisomerase I (TopA), that functions in the replication of the telomeric regions of linear chromosomes, plasmids and circular replicons of some bacterial species.

Catalysis of the reaction: N-acetyl-L-2,6-diaminoheptanedioate + 2-oxoglutarate = N-acetyl-2-L-amino-6-oxoheptanedioate + L-glutamate.

Catalysis of the reaction: CDP-digeranylgeranylglycerol + L-serine = archaetidylserine + CMP.

Binds to and modulates the activity of UTP:glucose-1-phosphate uridylyltransferase.
