WebThe cis and trans isomers of butenedioic acid display very different reactivities, which can be attributed to the difference in their properties. Maleic acid is the cis isomer … WebSince the auto-conversion of trans - to cis-proline is slow, the cis / trans isomerization becomes the rate limiting step for the reaction catalyzed by Ssu72 (Figure 4C) [25,32]. Now, proline isomerases (e.g., Pin1 and Ess1) catalyze the cis / trans conversion and thus may contribute to rebalancing the substrate pool for Ssu72 [ 25 ].
