Surface proteins of gram-positive bacteria and mechanisms of their targeting to the cell wall envelope

Article Abstract:

The cell wall of gram-positive microorganisms does not only act as a shield against harmful foreign compounds, but also functions as an anchor for protein synthesis. Results gathered from a DNA analysis involving Escherichia coli strains revealed that protein translocation in the cellular wall is made possible through the action of signal peptides. These peptides, which are typically composed of 15 to 20 hydrophobic residues, ensure that the protein translocation process is carried out efficiently.

Cellulase, clostridia, and ethanol

Article Abstract:

The study discusses the need for processes, the cellulases of clostridia, their presence in extracellular complexes or organelles, the binding of the cellulosomes to cellulose and to the cell surface, cellulase genetics, regulation of their synthesis, cocultures, ethanol tolerance and metabolic pathway engineering for maximizing ethanol yield.
