Pneumococcal surface protein A (PspA) of Streptococcus pneumoniae has been found to utilize a novel mechanism for anchoring to the bacterial cell surface. In contrast to that of surface proteins from other gram-positive bacteria, PspA anchoring required choline-mediated interactions between the membrane-associated lipoteichoic acid and the C-terminal repeat region of PspA. Release of PspA from ...
The unicellular alga Chlamydomonas reinhardtii is surrounded by a cell wall composed entirely of hydroxyproline-rich glycoproteins (HRGPs). When the walls of vegetative cells are removed with the enzyme gamete autolysin (g-lysin), they regenerate a matrix within 3-4 hr. In vitro translation of mRNAs isolated from g-lysin-treated cells showed significant increases and decreases in abundance of s...
Streptococcus pneumoniae is a major pathogen leading to substantial morbidity and mortality in children under 5 years of age. Vaccination is an effective strategy to prevent S. pneumoniae infection. SPY1 is a pneumococcal vaccine candidate strain obtained in our previous study. To improve its stability and immunogencity, in this study, we constructed the SPY1ΔlytA strain that lacks autolysin ac...
The emergence of tolerance to vancomycin has recently been reported in Streptococcus pneumoniae, the most common cause of bacterial meningitis. A vancomycin- and cephalosporin-tolerant strain of S. pneumoniae, the Tupelo strain, was isolated from the cerebrospinal fluid of a patient who then developed recrudescence of meningitis despite treatment with vancomycin and a third-generation cephalosp...
