Biochemical and structural characterization of a tail‐spike protein with depolymerase activity identified in a marine podovirus

Acta Crystallographica Section D, EarlyView.
The marine tail‐spike protein Dpo31 degrades the exopolysaccharide of its host and has structural features similar to those of other members of this protein class, despite similarity not being detected at the sequence level.Marine phages are, through the infection of their bacterial hosts, key regulators of microbiome and carbon fluxes in the ocean ...
