Sorry, no etymologies found.
The requirement for one base and one electrophile may be a major factor in preserving the cis-enediol mechanism in evolution.
This implies a cis-enediol intermediate. cis-enediol intermediates have the advantage of requiring only
A relation between the cis-enediol mechanism and the anomeric specificity of isomerases.
The proposed intermediate, EH. enediol-P was found to partition about equally in the forward and back direction as shown by the equal incorporation of
Since ring closing is the reverse of ring opening, we wondered if enzymes with a cis-enediol intermediate would be defined in the ring closing step.
For these proton transfers to have been intramolecular, they would both have come from the same face of the enediol intermediates.
