  • Title: Construction and characterization of hybrids containing genes coding for proteins of the central part of bacteriophage T4 baseplate.
    Author: Nieradko J, Szewczyk B.
    Journal: Acta Microbiol Pol; 1990; 39(1-2):13-22. PubMed ID: 1715636.
    Abstract:
    The central part (hub or plug) of bacteriophage T4 baseplate consist of several proteins which are present in only few copies per phage particle. The presence of these minor baseplate components was inferred from the genetic data but only some of them were identified as distinct proteins species by biochemical analysis. We have constructed a number of plasmids containing segments of bacteriophage T4 genome coding for baseplate proteins. The following genes were cloned into expression vectors: 54, 48, 29, 28, 27, 51, 26 and 25. The presence of a particular gene product was confirmed by in vivo complementation test. On the basis of these results we could more precisely localize the position of a particular gene on T4 phage genetic map. The hybrids contain sets of genes which make aggregation impossible, so bacteria harbouring these plasmids are convenient starting point for the purification of baseplate proteins.
