A SecA-associated protease modulates the extent of surface display of staphylococcal protein A

Journal of Bacteriology
In bacteria, signal peptides direct pre-proteins to the SecYEG secretion channel and are typically cleaved by signal peptidases during translocation across the membrane.

A novel polysaccharide in the envelope of S. aureus influences the septal secretion of preproteins with a YSIRK/GXXS motif

Journal of Bacteriology
Bacteria transport proteins across the plasma membrane to assemble their envelope, acquire nutrients, and establish appropriate interactions with their environment.

A Computational Simulation Study of Fluid Mechanics of Low-Speed Wind Tunnel Contractions

Fluids, 2017
In this work, the fluid mechanics performance of four different contraction wall shapes has been studied and compared side-by-side by computational simulation, and the effect of contraction cross-sectional shape on the flow uniformity at the contraction ...

Processing of LtaS restricts LTA assembly and YSIRK preprotein trafficking into Staphylococcus aureus cross-walls

mBio
Septal membranes of Staphylococcus aureus serve as the site of secretion for precursors endowed with the YSIRK motif. Depletion of ltaS, a gene required for lipoteichoic acid (LTA) synthesis, results in the loss of restricted trafficking of YSIRK ...

Influence of the wall thickness value on the cross wall thickness deviation of tubes rolled on the tube rolling plant with the continuous mill [PDF]

Журнал інженерних наук, 2018
The high requirements as to accuracy of the wall thickness are due not only to necessity of assuring the reliability and serviceability of equipment, but also to the trend towards the continuous decrease of metal capacity.

Changes in cell wall properties coincide with overexpression of extensin fusion proteins in suspension cultured tobacco cells.

PLoS ONE, 2014
Extensins are one subfamily of the cell wall hydroxyproline-rich glycoproteins, containing characteristic SerHyp4 glycosylation motifs and intermolecular cross-linking motifs such as the TyrXaaTyr sequence.

The GPI-Anchored GH76 Protein Dfg5 Affects Hyphal Morphology and Osmoregulation in the Mycoparasite Trichoderma atroviride and Is Interconnected With MAPK Signaling

Frontiers in Microbiology, 2021
The fungal cell wall is composed of a cross-linked matrix of chitin, glucans, mannans, galactomannans, and cell wall proteins with mannan chains. Cell wall mannans are directly attached to the cell wall core, while the majority of mannoproteins is ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Cell wall assembly in Bacillus megaterium: incorporation of new peptidoglycan by a monomer addition process [PDF]

, 1991
The pattern of cross-linking in the peptidoglycan of Bacillus megaterium has been studied by the pulsed addition of radiolabeled diaminopimelic acid.
