Nucleotide sequence of the gene presumably encoding the adsorption protein of filamentous phage φLf

Abstract

A 1170-nucleotide fragment of φLf DNA was sequenced. This fragment contains an open reading frame, ORF367, encoding a protein of 367 amino acids (aa) (36710 Da). ORF367 is located downstream from the gene encoding the major coat protein (gVIIIp) and a Rho-independent termination signal. Sequence analysis revealed that the gene product has a Gly-rich domain (70 aa) at the center and a hydrophobic region (26 aa) at the C terminus. These structural features suggest that ORF367 may encode the adsorption protein of φLf.
