4-Hydroxybenzoate geranyltransferase
class of enzymes
4-hydroxybenzoate geranyltransferase (EC 2.5.1.93, PGT1, PGT2, 4HB geranyltransferase, 4HB:geranyltransferase, p-hydroxybenzoate geranyltransferase, PHB geranyltransferase, geranyl diphosphate:4-hydroxybenzoate geranyltransferase) is an enzyme with systematic name geranyl-diphosphate:4-hydroxybenzoate 3-geranyltransferase. This enzyme catalyses the following chemical reaction
geranyl diphosphate + 4-hydroxybenzoate
⇌
{\displaystyle \rightleftharpoons }
3-geranyl-4-hydroxybenzoate + diphosphate
The enzyme is involved in shikonin biosynthesis. It has a strict substrate specificity for geranyl diphosphate and an absolute requirement for Mg2+.
The public source identifies “4-Hydroxybenzoate geranyltransferase” as class of enzymes. This brief keeps that definition visible, then builds a research path around 4-Hydroxybenzoate, geranyltransferase and class.
Why this record matters
A short description can identify a subject without explaining its stakes. For “4-Hydroxybenzoate geranyltransferase”, the useful work is to connect “class of enzymes” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 3, 2025. The linked authority identifier is Q7766809. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
