Bioconversion of m-hydroxybenzoate to 2,3-dihydroxybenzoate by mutants of Pseudomonas testosteroni.

abstract：:In this study, we demonstrated the remarkable genome plasticity of lytic lactococcal phages that allows them to rapidly adapt to the dynamic dairy environment. The lytic double-stranded DNA phage ul36 was used to sequentially infect a wild-type strain of Lactococcus lactis and two isogenic derivatives with genes encod...

Pinholins require secreted SAR endolysins, a pairing that may represent an intermediate in the evolution of canonical holin-endolysin systems. ...
