Yersinia enterocolitica-Specific Infection by Bacteriophages TG1 and ϕR1-RT Is Dependent on Temperature-Regulated Expression of the Phage Host Receptor OmpF [PDF]

open access: yes, 2016
Bacteriophages present huge potential both as a resource for developing novel tools for bacterial diagnostics and for use in phage therapy. This potential is also valid for bacteriophages specific for Yersinia enterocolitica. To increase our knowledge of

Is rat an appropriate animal model to study the involvement of d-serine catabolism in schizophrenia? insights from characterization of d-amino acid oxidase. [PDF]

open access: yes, 2011
d-Amino acid oxidase (DAAO; EC1.4.3.3) has been proposed to play a main role in the degradation of d-serine, an allosteric activator of the N-methyl-d-aspartate-type glutamate receptor in the human brain, and to be associated with the onset of ...

Cloning, purification, and functional characterization of Carocin S2, a ribonuclease bacteriocin produced by Pectobacterium carotovorum [PDF]

open access: yes, 2011
Background Most isolates of Pectobacterium carotovorum subsp. carotovorum (Pcc) produce bacteriocins. In this study, we have determined that Pcc strain F-rif-18 has a chromosomal gene encoding the low-molecular-weight bacteriocin, Carocin S2, and that ...
