CRYSTALLIZATION AND PRELIMINARY CRYSTALLOGRAPHIC STUDIES OF RIBULOSE 1,5-BISPHOSPHATE CARBOXYLASE OXYGENASE FROM A RED ALGA, GALDIERIA-PARTITA, WITH A HIGH SPECIFICITY FACTOR/

Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) from a red a lga, Galdieria partita, has been crystallized by the hanging drop vapo r diffusion method, Two forms (Forms I and II) of crystals were obtain ed under distinct conditions, The Form I crystal belongs to monoclinic space group C2 with cell dimensions of a=190.2, b=140.0, c=189.0 A, a nd beta=102.6, and diffracts up to 3.0 Angstrom resolution, Diffractio n from the Form II crystal was too weak to determine crystal data.
