Unexpected relationships between bacteriophage lambda hypothetical proteins and bacteriophage T4 tail-fiber proteins

Hypothetical lambda protein ORF314 shows significant homology with the carboxyl end of phage T4 tail-fiber protein gp37. Homology can also be demonstrated between hypothetical lambda protein ORF194 and a fragment of bacteriophage T4 protein gp38. This sequence homology is also reflected in the genomic sequences of these two phages.
