In the ER, combined action of UGGT and G-II (cleavage-2) interconverts
M9 and G1M9 glycoforms.
21) The significance of these cis, trans dienoic acids is complicated by the fact that in mammals, lipids are stored for practical purposes solely as saturated fat, and that in processing, the enoyl-coenzyme A isomerase system (22) interconverts
cis, trans dienoic acids.
Also involved in capsular biosynthesis is phosphoglucomutase, a 571-aa protein encoded by pgmA that interconverts
glucose 6-phosphate and glucose 1-phosphate (33).
We have recently employed this method in a study of the enzyme malate dehydrogenase, which interconverts
malate and oxaloacetate by means of a proton and a hydride transfer.
It may be found that MJ is yet more potent, because the more biologically active of the four possible stereoisomers, (-)jasmonate, readily interconverts
to the less active (+)jasmonate in commercial preparations.
