Crotonyl-CoA

Crotonyl-coenzyme A is an intermediate in the fermentation of butyric acid, and in the metabolism of lysine and tryptophan.^[1] It is important in the metabolism of fatty acids and amino acids.^[2]

Crotonyl-CoA and reductases

Before a 2007 report by Alber and coworkers, crotonyl-CoA carboxylases and reductases (CCRs) were known for reducing crotonyl-CoA to butyryl-CoA.^[3] A report by Alber and coworkers concluded that a specific CCR homolog was able to reduce crotonyl-CoA to (2S)-ethyl malonyl-CoA which was a favorable reaction.^[3] The specific CCR homolog came from the bacterium Rhodobacter sphaeroides.^[3]

Role of Crotonyl-CoA in Transcription

Post-translational modification of histones either by acetylation or crotonylation is important for the active transcription of genes.^[4] Histone crotonylation is regulated by the concentration of crotonyl-CoA which can change based on environmental cell conditions or genetic factors.^[4]
