The riddle of the plant vacuolar sorting receptors [PDF]
Protoplasma 226 (12/2005) 103-8, 2006 Proteins synthesized on membrane-bound ribosomes are sorted at the Golgi apparatus level for delivery to various cellular destinations: the plasma membrane or the extracellular space, and the lytic vacuole or lysosome. Sorting involves the assembly of vesicles, which preferentially package soluble proteins with a common destination.

A peptidoglycan hydrolase motif within the mycobacteriophage TM4 tape measure protein promotes efficient infection of stationary phase cells [PDF]
, 2006 The predominant morphotype of mycobacteriophage virions has a DNA-containing capsid attached to a long flexible non-contractile tail, features characteristic of the Siphoviridae.

Bacteriophage-encoded virion-associated enzymes to overcome the carbohydrate barriers during the infection process [PDF]
, 2017 Bacteriophages are bacterial viruses that infect the host after successful receptor recognition and adsorption to the cell surface. The irreversible adherence followed by genome material ejection into host cell cytoplasm must be preceded by the passage ...

Lytic transglycosylase Slt of Pseudomonas aeruginosa as a periplasmic hub protein. [PDF]
Protein SciAbstractPeptidoglycan is a major constituent of the bacterial cell wall. Its integrity as a polymeric edifice is critical for bacterial survival and, as such, it is a preeminent target for antibiotics. The peptidoglycan is a dynamic crosslinked polymer that undergoes constant biosynthesis and turnover.

Well-temperate phage: optimal bet-hedging against local environmental collapses [PDF]
Scientific Reports 5, Article number: 10523 (2015), 2013 Upon infection of their bacterial hosts temperate phages must chose between lysogenic and lytic developmental strategies. Here we apply the game-theoretic bet-hedging strategy introduced by Kelly to derive the optimal lysogenic fraction of the total population of phages as a function of frequency and intensity of environmental downturns affecting the ...

Molecular characterisation, evolution and expression analysis of g-type lysozymes in Ciona intestinalis [PDF]
, 2017 Lysozyme is an important defense molecule of the innate immune system. Known for its bactericidal properties, lysozyme catalyzes the hydrolysis of b-(1,4)-glycosidic bonds between the N-acetyl glucosamine and N-acetyl muramic acid in the peptidoglycan ...

Crystal Structures of the SpoIID Lytic Transglycosylases Essential for Bacterial Sporulation [PDF]
Journal of Biological Chemistry, 2016 Bacterial spores are the most resistant form of life known on Earth and represent a serious problem for (i) bioterrorism attack, (ii) horizontal transmission of microbial pathogens in the community, and (iii) persistence in patients and in a nosocomial environment.

Slowly replicating lytic viruses: pseudolysogenic persistence and within-host competition [PDF]
Phys. Rev. Lett. 102, 178103 (2009), 2008 We study the population dynamics of lytic viruses which replicate slowly in dividing host cells within an organism or cell culture, and find a range of viral replication rates that allows viruses to persist, avoiding extinction of host cells or dilution of viruses at too rapid or too slow viral replication.

Structure of the stationary phase survival protein YuiC from B.subtilis [PDF]
, 2015 - Background: Stationary phase survival proteins (Sps) were found in Firmicutes as having analogous domain compositions, and in some cases genome context, as the resuscitation promoting factors of Actinobacteria, but with a different putative ...
