Journal ArticleDOI
Sequences of three genes specifying xylanases in Streptomyces lividans.
TL;DR: The entire nucleotide (nt) sequences of three genes (xlnA, xlnB and xlnC) of Streptomyces lividans encoding three distinct xylanases (Xln) have been determined and showed some homology with either the N- termini or the C-termini of eight other Xln and of two exo-glucanases.
Journal ArticleDOI
Homologous cloning, expression, and characterisation of a laccase from Streptomyces coelicolor and enzymatic decolourisation of an indigo dye
TL;DR: This enzyme was able to rapidly decolourise the dye in the presence of syringaldehyde as a redox mediator and was found to be quite resistant under various conditions.
Journal ArticleDOI
Capacity of human nisin- and pediocin-producing lactic Acid bacteria to reduce intestinal colonization by vancomycin-resistant enterococci.

TL;DR: This study demonstrated the capacity of bacteriocin-producing lactic acid bacteria (LAB) to reduce intestinal colonization by vancomycin-resistant enterococci (VRE) in a mouse model and showed that human L. lactis and P. acidilactici nisin- and pediocIn-producing strains can reduce VRE intestinal colonization.
Journal ArticleDOI
Structure and activity of two metal ion-dependent acetylxylan esterases involved in plant cell wall degradation reveals a close similarity to peptidoglycan deacetylases.

TL;DR: The structures of two distinct acetylxylan esterases, those from Streptomyces lividans and Clostridium thermocellum, in native and complex forms are reported, showing that the enzymes are sugar-specific and metal ion-dependent and possess a single metal center with a chemical preference for Co2+.
Journal ArticleDOI
Purification and properties of a xylanase from Streptomyces lividans.
TL;DR: An extracellular xylanase produced by a cellulase-negative mutant strain of Streptomyces lividans 1326 was purified to homogeneity, indicating that it is a beta-1,4-endoxylanase (EC 3.2.8), and showed no activity towards CM-cellulose and p-nitrophenyl beta-D-xyloside.
