Pantothenate Kinase Pathway (None)

Target
None
Molecular classification
Enzyme Pathway
01

Overview

The pantothenate kinase pathway refers to the biochemical sequence responsible for the phosphorylation of pantothenate (vitamin B5) as the first and rate-limiting step in coenzyme A (CoA) biosynthesis. The key enzyme, pantothenate kinase (PanK; EC 2.7.1.33), catalyzes this ATP-dependent reaction, converting pantothenate into 4'-phosphopantothenate. This pathway is essential for all living organisms due to CoA’s central role in metabolism. Mutations or dysregulation are linked to neurodegenerative diseases such as PKAN (pantothenate kinase-associated neurodegeneration) and may also play a role in cancer progression.
