Studies Conducted at Jilin University on Gram-Negative Bacteria Recently Reported

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Gram-Negative Bacterial Infections. According to news originating from Changchun, People's Republic of China, by NewsRx correspondents, research stated, "Peptidoglycan recognition proteins (PGRPs) are secreted innate immunity pattern recognition molecules. In this study, a new peptidoglycan recognition protein 1 named cnPGRP1 was isolated from an antler base of sika deer Cervus nippon."

Our news journalists obtained a quote from the research from Jilin University, "The antler base antimicrobial proteins (AAP) were subjected to consecutive chromatographic methods connected to Sephadex G-25 gel filtration column (CM) anion-exchange column, and RP-HPLC. The molecular weight of cnPGRP1 was 17.2 kDa under SDS-PAGE, and peptide mass fingerprint analysis by MALDI-TOF-MS as peptidoglycan recognition protein 1 matched to Dasypus novemcinctus. The matched amino acids sequences were RLYEIIQICWPHYRA. Both Gram-positive and Gram-negative bacteria can be killed by cnPGRP1 in the 50-250 mu g/mL range through in vitro."

According to the news editors, the research concluded: "Furthermore, cnPGRP1 has been found to bind Gram-positive bacteria, Gram-negative bacteria, and even fungus."
