With Sam, James made a new start with what would today be called cell biology, the isolation of "chloroplasts, mitochondria, cytoplasm, and lots of enzymes!" They ground spinach leaves in a colloid mill, centrifuged the product at 20,000gn and found that the supernatant contained the soluble leaf proteins. Furthermore, over half of the soluble leaf proteins consisted of a single component of molecular mass ca. 500,000, which they called fraction I. Sam found this fraction in many other leaves besides spinach. It was later shown by John Littleton of Palmerston North, New Zealand, a former postdoctoral fellow of James, that fraction I was the main protein in the stroma or fluid part of chloroplasts. He, Paul Ts'o, and others went on to show that fraction I is ribulose-1,5-bisphosphate carboxylase/oxidase, which is now often referred to as rubisco. Rubisco is the enzyme that fixes CO2 in photosynthesis. It is the most abundant protein in the world, and Sam Wildman continued to study it until he retired."
