Gram+ Gram- Schematic diagram of bacterial cell walls Bacteria can be divided into two major groups, called gram-positive and gram-negative. The original distinction between gram-positive and gram-negative was based on a special staining procedure, the Gram stain. Teichoic acids and lipoteichoic ...

[67] suggested that the distribution pattern of lysin domains might be related to cell wall structure (mycoplasmas, Gram-negative, and Gram-positive) and not bacterial species due to the conservation of the structure of the cell wall. All the lysins evaluated in this study were encoded by ...

Surface, secreted and transmembrane protein-encoding open reading frames, collectively the secretome, can be identified in bacterial genome sequences using bioinformatics. However, functional analysis of translated secretomes is possible only if many sec
Strain CF6-2 lyses Gram-positive bacterial cells by secreting the metalloprotease pseudoalterin to degrade the PG in Gram-positive bacterial cell wall, which leads to the collapse of the cell wall and subsequent lysis of the cell. Then, strain CF6-2 utilizes the d/l-amino acids and the ol...

ClpXP plays an integral role in bacterial viability by degrading damaged and misfolded proteins, and is strongly associated with virulence in Gram-positive pathogens, including S. aureus, S. pneumoniae, and Enterococcus faecalis (Cassenego et al., 2016; Frees et al., 2003; Kwon et al., 2004...
ultimately leading to decreased membrane integrity and cell death15. The potent antibacterial activity of friulimicin and its structural relatives is due to inhibition of bacterial cell wall biosynthesis through binding of the lipid II precursor, undecaprenyl phosphate (C55-P)16,17. As the malacidin...
