Cystathionine Beta Synthase (CBS)

🔬 Protein Info
Gene SymbolCBS
AliasesCBSPROTEIN
FunctionCystathionine Beta Synthase (CBS) is a pyridoxal phosphate (PLP)-dependent enzyme that catalyzes the condensation of serine and homocysteine to form cystathionine, a critical intermediate in the tr...

Dimeric assemblyEach monomer contains N-terminal catalytic and C-terminal regulatory domains
Tetramer formationDimers can further associate into tetramers, enhancing stability
Allosteric regulationSAM binding to C-terminal domains propagates conformational changes to the catalytic site
Active site geometryThe PLP Schiff base is positioned for optimal catalysis with substrates
S-adenosylmethionine (SAM) bindingPrimary allosteric activator
S-adenosylhomocysteine (SAH) inhibitionProduct inhibitor
Heme bindingStabilizes the protein structure
Oxidative modificationsReactive oxygen species can inhibit activity
PhosphorylationSeveral kinases may regulate CBS activity
