Cyclic pyranopterin monophosphate
Precursor Z hydrate is a linear-fused organic heterotetracyclic compound consisting of a [1,3,2]dioxaphosphinane fused to a pyran ring which is in turn fused to a pteridine ring system. Molybdenum cofactor biosynthesis intermediate. Dehydrated derivative known as precursor Z. It has a role as an Escherichia coli metabolite. It is an organic heterotetracyclic compound, an oxacycle, an organonitrogen heterocyclic compound and a ketone hydrate.
