Processing of the tail lysozyme (gp5) of bacteriophage T4.

The processing site of gp5 has been determined to be between residues Val-390 and His-391, instead of Ser-351 and Ala-352 as previously reported (H. Kanamaru, N. C. Gassner, N. Ye, S. Takeda, and F. Arisaka, J. Bacteriol. 181:2739-2744). Moreover, the maturation of gp5 is abolished by null mutations in other hub genes, indicating that cleavage requires the interactions of several baseplate proteins.
