The amino acid sequence of crystalline sheets: a proteolytic fragment of the major head protein (gP23) of bacteriophage T4.
A peptide, obtained from T4 phage major capsid protein gP23 by chymotryptic digestion, has been shown to form two types of crystalline sheets, hexagonal and rectangular. The sheet peptide was subjected to conventional sequencing work. Together with the DNA sequence of gene 23, the results showed that the peptide consisted of 155 amino acids, located from 295 to 449 in the nascent gP23 and from 230 to 384 in the matured gP23.
