Microbial Cell Factories, 2022 Background Bacterial type III secretion systems (T3SSs) assemble a multiprotein complex termed the injectisome, which acts as a molecular syringe for translocation of specific effector proteins into the cytoplasm of host cells.

Deletion of Lytic Transglycosylases Increases Beta-Lactam Resistance in Shewanella oneidensis [PDF]
Frontiers in Microbiology, 2018 Production of chromosome-encoded β-lactamases confers resistance to β-lactams in many Gram-negative bacteria. Some inducible β-lactamases, especially the class C β-lactamase AmpC in Enterobacteriaceae, share a common regulatory mechanism, the ampR-ampC paradigm.

Regulation of biofilm formation in Salmonella typhimurium and Escherichia coli Nissle 1917 [PDF]
, 2011 Bacteria have the ability to grow in cell communities designated biofilms. This mode of growth is widespread and offers numerous advantages to the bacteria in terms of survival, persistence and propagation.

The catalytic domain of a bacterial lytic transglycosylase defines a novel class of lysozymes [PDF]
Proteins: Structure, Function, and Bioinformatics, 1995 AbstractThe 70‐kDa soluble lytic transglycosylase (SLT70) from Escherichia coli is a bacterial exo‐muramidase that cleaves the cell wall peptidoglycan, producing 1,6‐anhydro‐muropeptides. The X‐ray structure of SLT70 showed that one of its domains is structurally related to lysozyme, although there is no obvious similarity in amino acid sequence.

A Novel Salmonella Periplasmic Protein Controlling Cell Wall Homeostasis and Virulence
Frontiers in Microbiology, 2021 Horizontal gene transfer has shaped the evolution of Salmonella enterica as pathogen. Some functions acquired by this mechanism include enzymes involved in peptidoglycan (PG) synthesis and remodeling.

Is density functional theory accurate for lytic polysaccharide monooxygenase enzymes? [PDF]
Dalton Trans., 2020,49, 1501, 2019 The lytic polysaccharide monooxygenase (LPMO) enzymes boost polysaccharide depolymerization through oxidative chemistry, which has fueled the hope for more energy-efficient production of biofuel. We have recently proposed a mechanism for the oxidation of the polysaccharide substrate (Hedeg{\aa}rd & Ryde, Chem. Sci. 2018, 9, 3866).

Resuscitation-promoting factors possess a lysozyme-like domain [PDF]
, 2004 The novel bacterial cytokine family – resuscitation-promoting factors (Rpfs) – share a conserved domain of uncharacterized function. Predicting the structure of this domain suggests that Rpfs possess a lysozyme-like domain.

Differential epitope recognition in the immunodominant staphylococcal antigen A of Staphylococcus aureus by mouse versus human IgG antibodies [PDF]
, 2017 The immunodominant staphylococcal antigen A (IsaA) is a potential target for active or passive immunization against the important human pathogen _Staphylococcus aureus_.

Lambda-prophage induction modeled as a cooperative failure mode of lytic repression [PDF]
, 2008 We analyze a system-level model for lytic repression of lambda-phage in E. coli using reliability theory, showing that the repressor circuit comprises 4 redundant components whose failure mode is prophage induction. Our model reflects the specific biochemical mechanisms involved in regulation, including long-range cooperative binding, and its detailed ...
