Methionine metabolism, leading to the biosynthesis of ethylene in Saccharomyces cerevisiae does not appear to involve S-adenosylmethionine (SAM) and aminocyclopropanecarboxylic acid (ACC), based on the lack of ethylene synthesis when both SAM and ACC were incubated in the presence and absence of cells. Thus, the mechanism leading to the formation...
Streptococcus pneumoniae and Influenza A Virus both primarily infect the upper respiratory tract, with more severe disease occurring during coinfection than would be caused by either pathogen independently. Until recently, characterization of the interactions between these two pathogens has occurred exclusively in the context of a host or using host-derived...
