PURIFICATION OF RIBULOSE 1,5‐BISPHOSPHATE CARBOXYLASE AND CARBON ISOTOPE FRACTIONATION BY WHOLE CELLS AND CARBOXYLASE FROM CYLINDROTHECA SP. (BACILLARIOPHYCEAE.)1,2,3

“…The average I'ractionation value of -32.6%<i (Table 3) can be compared with Iraitionatiou values by RnBI' carboxylase IVom Agrnvnt'lliim tfuadrujfUaiium (-32.l%f), and the photosynthetic bacteria Rhoitn.sftirillum nihriim (-32.2%(), and Hhodnfjscudomanm sf)h(ini)i(hs (a\'g. -29.8^^r), procaryotic organisms which contain a full range of structurally and tatalytically distinct RuRP carboxylases (15). This suggests that the reaction mechanism of the diatom carboxylase is similar to en/yme obtained from other organisms, thus intermediate 5'X.…”
