zur: a Zn(super.2+)-responsive regulatory element of Staphylococcus aureus

Article Abstract:

A Staphylococcus aureus Zn(super.2+)-responsive regulatory element is discussed. The putative operon, zur, and components of an ABC-type transporter have been characterized, and it appears zur has no role in pathogenicity in a lesion model of S. aureus infection..

Characterization of AcmB, an N-acetylglucosaminidase autolysin from Lactococcus lactis

Article Abstract:

Research reveals that the autolysin AcmB from Lactococcus lactis exhibits a modular structure with an N-terminal -, a central-, and a C-terminal domain. Data indicate that AcmB shows N-acetylglucosaminidase specificity and participates in cellular autolysis.
