Cis trans bonds
Web[4] [5] [6] As a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family, this protein catalyzes the cis-trans isomerization of proline imidic peptide bonds, which allows it to regulate many biological processes, including intracellular signaling, transcription, inflammation, and apoptosis. WebCis means “on the same side”, trans means “on opposing sides”. In the cis isomer, the substituent groups are placed on one side, while in the trans isomer, the substituent groups are placed on different sides of a double …
