ABSTRACT | Lactococcal phages Tuc2009 and TP901-1 possess a conserved tail fiber called a tail-associated lysin (referred to as Tal(2009) for Tuc2009, and Tal(901-1) for TP901-1), suspended from their tail tips that projects a peptidoglycan hydrolase domain toward a potential host bacterium. Tal(2009) and Tal(901-1) can undergo proteolytic processing mid-protein at the glycine-rich sequence GG(S/N)SGGG, removing their C-terminal structural lysin. In this study, we show that the peptidoglycan hydrolase of these Tal proteins is an M23 peptidase that exhibits D-Ala-D-Asp endopeptidase activity and that this activity is required for efficient infection of stationary phase cells. Interestingly, the observed proteolytic processing of Tal(2009) and Tal(901-1) facilitates increased host adsorption efficiencies of the resulting phages. This represents, to the best of our knowledge, the first example of tail fiber proteolytic processing that results in a heterogeneous population of two phage types. Phages that possess a full-length tail fiber, or a truncated derivative, are better adapted to efficiently infect cells with an extensively cross-linked cell wall or infect with increased host-adsorption efficiencies, respectively. | ||
