ABSTRACT
The structural protein, gene product 9 (gp9), of bacteriophage T4 controls baseplate expansion at the first steps of virus attachment onto its host bacterial cell with subsequent tail contraction. Gp9, which has an M(r) of 30.8 kDa and contains 287 amino acids, has been purified from a recombinant Escherichia coli strain and crystallized at 25 degrees C using the hanging drop vapor diffusion method at pH 4.0 with ammonium sulfate as precipitant. The crystals of gp9 belong to the space group R32 with hexagonal cell dimensions a = b = 86.5 A and c = 156.2 A and diffract X-rays to at least 2.7 A. There is one molecule per asymmetric unit.
