||P.1844 left column 2nd paragraph: "This includes an especially large investment in RuBisCO, which has a relatively low catalytic rate and represents up to half of leaf protein (primary sources)." Primary source Ellis p.241 left column top paragraph: "The strongest candidate for the most abundant protein in nature is a high molecular weight soluble protein first purified from spinach leaves by Wildman and Bonner [ref 1], and named by them Fraction I protein. The most striking feature of this protein is the large quantity in which it occurs in all photosynthetic leaves, up to 65% of the total soluble protein in leaf extracts is accounted for by this single species, which is homogeneous by electrophoretical and ultracentrifugal criteria."
