摘要: Trophosome tissue of the hydrothermal vent tube worm, Riftia pachyptila (Vestimentifera), contains high activities several enzymes associated with chemoautotrophic existence. Enzymes catalyzing synthesis adenosine triphosphate using energy contained in sulfur compounds such as hydrogen sulfide, and two diagnostic Calvin-Benson cycle carbon dioxide fixation, ribulosebisphosphate carboxylase ribulose 5-phosphate kinase, are present at levels trophosome, but absent muscle. These data consistent an autotrophic mode nutrition for this which lives sulfide-rich waters lacks a mouth digestive system.
