Carbon is the backbone of life on Earth. Converting it into biomass is the job of primary producers—organisms that fix carbon from CO2 and transform it into organic molecules. Out of the seven known pathways organisms use to fix CO2, many modern primary producers employ the microbial acetyl-CoA pathway to fix carbon. The study “Protein […] The post #FEMSmicroBlog: What carbon-fixating microbial enzymes tell us about evolution appeared first on FEMS .
