In biochemistry, cis-trans isomerase is a type of isomerase which catalyzes the isomerization of geometric isomers. Examples include retinal isomerase and immunophilins such as cyclophilin . External links
Very often, cis–trans stereoisomers contain double bonds or ring structures. In both cases the rotation of bonds is restricted or prevented. [4] When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas when the substituents are oriented in opposing directions, the diastereomer is referred to as trans.
Prolyl isomerase (also known as peptidylprolyl isomerase or PPIase) is an enzyme (EC 5.2.1.8) found in both prokaryotes and eukaryotes that interconverts the cis and trans isomers of peptide bonds with the amino acid proline. [1]
The isomerization energy, for example, for converting from a stable cis isomer to the less stable trans isomer is greater than for the reverse reaction, explaining why in the absence of isomerases or an outside energy source such as ultraviolet radiation a given cis isomer tends to be present in greater amounts than the trans isomer.
Peptidyl-prolyl cis-trans isomerase B is an enzyme that is encoded by the PPIB gene. [5] 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 protein folding of type I collagen.

Peptidyl-prolyl cis-trans isomerase FKBP1A is an enzyme that in humans is encoded by the FKBP1A gene. [5] It is also commonly referred to as FKBP-12 or FKBP12 and is a member of a family of FK506 -binding proteins ( FKBPs ).
In enzymology, maleylacetoacetate isomerase (EC 5.2.1.2) is an enzyme that catalyzes the chemical reaction. 4-maleylacetoacetate 4-fumarylacetoacetate. This enzyme belongs to the family of isomerases, specifically cis-trans isomerases. The systematic name of this enzyme class is 4-maleylacetoacetate cis-trans-isomerase.
