Cis-trans isomerase
Encyclopedia
Cis-trans isomerase is a type of isomerase
which catalyzes the isomerization of geometric isomers.
Examples include photoisomerase
and immunophilins
such as cyclophilin
.
Isomerase
In biochemistry, an isomerase is an enzyme that catalyzes the structural rearrangement of isomers. Isomerases thus catalyze reactions of the formwhere B is an isomer of A.-Nomenclature:...
which catalyzes the isomerization of geometric isomers.
Examples include photoisomerase
Photoisomerase
A photoisomerase is a protein in the eye that is responsible for isomerizing photopigments.In order for the eye to function propertly, a special chemical called a chromophore is bound to a protein known as an opsin. When a photon strikes the chromophore, it changes shape . It is this change in...
and immunophilins
Immunophilins
In molecular biology, immunophilins are endogenous cytosolic peptidyl-prolyl isomerases that interconvert between the cis and trans positions.Immunophilins are targeted by immunosuppressive drugs such as rapamycin, ciclosporin, and tacrolimus...
such as cyclophilin
Cyclophilin
Cyclophilins are a family of proteins from vertebrates and other organisms that bind to cyclosporine, an immunosuppressant which is usually used to suppress rejection after internal organ transplants...
