Kinetic isotope effect and characterization of form II RubisCO from the chemoautotrophic endosymbionts of the hydrothermal vent tubeworm Riftia pachyptila


It has been hypothesized that the d13C values of chemoautotrophs at deep-sea hydrothermal vents, which cluster in two groups around 211‰ and 230‰, are due to variation in isotopic discrimination by different forms of RubisCO. The most enriched d13C values are from the vestimentiferan tubeworm Riftia pachyptila, whose bacterial endosymbionts provide… (More)
