Nucleotide sequence of bacteriophage T4 uvsY gene.

We have determined the nucleotide sequence of a 1001-bp region comprising the uvsY gene of bacteriophage T4. An open reading frame of 420 base pairs was found to encode the uvsY gene product. The uvsY gene comprised a 140-amino acid protein with ATG (methionine) as the initiation codon, which is consistent with the molecular weight determined by SDS-polyacrylamide gel electrophoresis. The uvsY gene was oriented in the direction of the early genes and a sequence common to the middle promoter consensus was found in the 5'-upstream region.
