Sysname
5-phospho-alpha-D-ribose-1-diphosphate:4-hydroxybenzoate 5-phospho-beta-D-ribofuranosyltransferase (decarboxylating)
Reaction(IUBMB)
5-phospho-alpha-D-ribose 1-diphosphate + 4-hydroxybenzoate = 4-(beta-D-ribofuranosyl)phenol 5'-phosphate + CO2 + diphosphate [RN:
R11102 ]
Reaction(KEGG)
Substrate
5-phospho-alpha-D-ribose 1-diphosphate [CPD:
C00119 ];
4-hydroxybenzoate [CPD:
C00156 ]
Product
4-(beta-D-ribofuranosyl)phenol 5'-phosphate [CPD:
C21107 ];
CO2 [CPD:
C00011 ];
diphosphate [CPD:
C00013 ]
Comment
The enzyme is involved in biosynthesis of tetrahydromethanopterin in archaea. It can utilize both 4-hydroxybenzoate and 4-aminobenzoate as substrates, but only the former is known to be produced by methanogenic archaea [4]. The activity is dependent on Mg2+ or Mn2+ [1].
