Structural analysis of bacteriophage-encoded peptidoglycan hydrolase domain KMV36C: crystallization and preliminary X-ray diffraction.

ABSTRACT

The C-terminus of gp36 of bacteriophage varphiKMV (KMV36C) functions as a particle-associated muramidase, presumably as part of the injection needle of the phiKMV genome during infection. Crystals of KMV36C were obtained by hanging-drop vapour diffusion and diffracted to a resolution of 1.6 A. The crystals belong to the cubic space group P432, with unit-cell parameters a = b = c = 102.52 A. KMV36C shows 30% sequence identity to T4 lysozyme (PDB code 1l56).
