Uroporphyrinogen III
Encyclopedia
Uroporphyrinogen III is an metabolic intermediate
in the biosynthesis
of protoporphyrin. It is created by the enzyme uroporphyrinogen III synthase
, and is converted into coproporphyrinogen III
by the enzyme uroporphyrinogen III decarboxylase
.
Metabolic intermediate
Metabolic intermediates refers to molecules which are the precursors or metabolites of biologically significant molecules.Although these intermediates are of relatively minor direct importance to cellular function, they can play important roles in the allosteric regulation of enzymes.-Clinical...

Biosynthesis
Biosynthesis is an enzyme-catalyzed process in cells of living organisms by which substrates are converted to more complex products. The biosynthesis process often consists of several enzymatic steps in which the product of one step is used as substrate in the following step...

Coproporphyrinogen III
In the metabolism of porphyrin, the enzyme uroporphyrinogen III decarboxylase generates coproporphyrinogen III from uroporphyrinogen III, and coproporphyrinogen III oxidase converts it into protoporphyrinogen IX....
