MicrobiologyOpen Publishes Issue 1.3
Our broad scope, open access Microbiology journal has now published its third issue. Editor-in-Chief, Pierre Cornelis has chosen the papers below to highlight:
Multiplicity of Salmonella entry mechanisms, a new paradigm for Salmonella pathogenesis by P. Velge, A. Wiedemann, M. Rosselin, N. Abed, Z. Boumart, A. M. Chaussé, O. Grépinet, F. Namdari, S. M. Roche, A. Rossignol and I. Virlogeux-Payant.
Abstract: This review focuses on the invasion mechanisms of Salmonella that have been described. The emerging theme, presented in this review, saying that Salmonella strains are able to enter non-phagocytic cells by various pathways independent of the classical type III secretion system should modify our view of Salmonella host specificity and of the mechanisms leading to the different diseases. (This is the first review to be published in the journal.)
An activator for pyruvoyl-dependent l-aspartate α-decarboxylase is conserved in a small group of the γ-proteobacteria including Escherichia coli by Shingo Nozaki, Michael E. Webb and Hironori Niki
Abstract: l-aspartate α-decarboxylase (ADC, PanD) is activated by the putative acetyltransferase YhhK (PanZ). Activation of PanD both in vivo and in vitro is PanZ-dependent. The putative acetyltransferases domain of PanZ may be responsible for activation to enhance the processing of PanD proenzyme. Regulation of PanD by PanZ allows these organisms to closely regulate production of pantothenate in response to metabolic demand.
Rad59 regulates association of Rad52 with DNA double-strand breaks by Nicholas R. Pannunzio, Glenn M. Manthey, Lauren C. Liddell, Becky Xu Hua Fu, Cai M. Roberts and Adam M. Bailis
Abstract: Genetic analysis of rad59 alleles using a translocation assay initiated by two simultaneous DNA double-strand breaks suggests that a key function of Rad59 in early stages of recombination is to facilitate removal of Rad51 filaments.
