Popis: |
The subunits (p28 and p86) of the isoenzyme form of eukaryotic initiation factor 4F (eIF-(iso)4F) from wheat were expressed separately in Escherichia coli. The subunits were purified by affinity chromatography (p28) and ion-exchange chromatography (p86). The purified subunits alone did not support polypeptide synthesis in an eIF-(iso)4F and eIF-4F-deficient translation system from wheat germ. However, when the two subunits were mixed together, activity equal to that of the native form of eIF-(iso)4F was obtained. These results show that subunits expressed separately are able to associate and form an enzymatically active complex. |
