ENZYME entry: EC 2.4.2.55

Accepted Name
Nicotinate D-ribonucleotide:phenol phospho-D-ribosyltransferase.
Reaction catalysed
Nicotinate D-ribonucleotide + phenol <=> nicotinate + phenyl 5-phospho-alpha-D-ribofuranoside
Comment(s)
  • The enzyme is involved in the biosynthesis of phenolic cobamides in the Gram-positive bacterium Sporomusa ovata.
  • It can also transfer the phospho-D-ribosyl group to 4-methylphenol and 5,6-dimethylbenzimidazole.
  • The related EC 2.4.2.21 also transfers the phospho-D-ribosyl group from nicotinate D-ribonucleotide to 5,6-dimethylbenzimidazole, but shows no activity with 4-methylphenol or phenol.
