Abstract:Background: Rubisco is among the most abundant enzymes on Earth and is a critical conduit for inorganic carbon into the biosphere. Despite this, the full extent of rubisco diversity and the biology of organisms that employ it for carbon fixation are still emerging, particularly in unlit ecosystems like the deep sea. Results: Here, we generate fifteen deeply-sequenced metagenomes along a spatially-resolved transect off the California coast, and combine them with globally-distributed public data to examine the d… Show more
