Extensive sequence homology in the DNA coding for elongation factor Tu from Escherichia coli and the Chlamydomonas reinhardtii chloroplast

J C Watson et al. Proc Natl Acad Sci U S A. 1982 Apr.

Abstract

Considerable DNA sequence homology can be detected between the Escherichia coli genes coding for translational components and Chlamydomonas reinhardtii chloroplast DNA. Labeled chloroplast DNA was found to hybridize to restriction fragments of the transducing phage lambda fus3 that code for elongation factor Tu. The chloroplast probe also reacts with fragments coding for ribosomal proteins carried by this phage. The region homologous to the elongation factor genes was located on the physical map of the chloroplast genome by probing restriction fragments of chloroplast DNA with cloned fragments, labeled in vitro, carrying the E. coli elongation factor Tu genes.
