Migration-glycosylation

PGE was isolated as desribed in Material and Methods. SDS-PAGE electrophoresis of purified protein showed a single band migrating at approximately 60 kDa. This observation is not in the agreement with the calculated molecular weight of 35 584. However a similar effect has been observed previously in case of PGI and PGC. Apart of the N-glycosylation which plays role in all PGs (Fig. 3), O-glycosylation may also be present as indicated by the band size shift after a treatment of PGE with O.IM NaOH (data not shown). [Pg.828]

A convenient preparation of 2-deoxy sugars [204] from glycosyl halides is based on the rapid and irreversible migration of an acyloxy group from C-2 to the anomeric center upon generation of the glycosyl radicals. This is a thermodynamically controlled reaction because it restores a d-a-d arrangement. [Pg.133]
