| Abstract: | Phage lambda major head protein, the gene E product, has been identified among other phage proteins synthesized in lambda-infected Escherichia coli minicells, separated by SDS-acrylamide gel electrophoresis. On stained gels, the same protein has also been detected among total (bacterial and phage) proteins of lambda-infected minicells. The contribution of lambda proteins to the total protein content of lambda-infected minicells was found to be about 12% following 30 min lambda-infection. The inhibition of lambda early protein synthesis (shown by other authors in nucleate bacterial cells) practically does not occur in minicells; this may be the reason of the observed high efficiency of phage protein synthesis. |
