2-Carboxy-3-keto-D-arabinitol 1,5-bisphosphate is a tightly bound intermediate of the carboxylase reaction of ribulosebisphosphate carboxylase/oxygenase. Two stereoisomers of an analog of this intermediate, 2-carboxy-D-arabinitol 1,5-bisphosphate (2CABP) and 4-carboxy-D-arabinitol 1,5-bisphosphate
The crystal structure of the binary complex of nonactivated ribulose-1,5-bisphosphate carboxylase/oxygenase from Rhodospirillum rubrum and a transition state analogue, 2-carboxy-D-arabinitol 1,5-bisphosphate has been determined to 2.6 A resolution with x-ray crystallographic methods. The transition
Ribulose 1,5-bisphosphate carboxylase/oxygenase has been purified from spinach and crystallized by equilibrium vapor diffusion with polyethylene glycol 6000 as a precipitant. Crystals suitable for x-ray studies were obtained from a binary complex with a transition state analogue,
Large single crystals of a quaternary complex of spinach ribulose bisphosphate carboxylase, Mg2+, CO2 and the transition state analogue 2-C-carboxy-D-arabinitol-1,5-bisphosphate have been obtained from ammonium sulfate solutions. These crystals belong to space group C222 with cell dimensions a =
Earlier structural and functional studies of ribulose-1,5-bisphosphate carboxylase/oxygenase imply that K334 facilitates the addition of gaseous substrate to the 2,3-enediol(ate) derived from ribulose 1,5-bisphosphate. Crystallographic analysis of the activated spinach enzyme [Knight et al. (1990)
2-C-Carboxy-D-glucitol 1,6-bisphosphate (CGBP) and 2-C-carboxy-D-mannitol 1,6-bisphosphate (CMBP) have been synthesized, isolated, and the structures of these compounds and the derived lactones elucidated by NMR spectroscopy and periodate oxidation. Both carboxyhexitol bisphosphates, which are
The large subunit (LS) of tobacco (Nicotiana rustica) ribulose-1,5-bisphosphate carboxylase/oxygenase (ribulose-P(2) carboxylase) contains a trimethyllysyl residue at position 14, whereas this position is unmodified in spinach ribulose-P(2) carboxylase. A protein fraction was isolated from tobacco
An expression plasmid incorporating the structural gene for the large subunit of a cyanobacterial ribulose-bisphosphate carboxylase, but not the gene for its complementary small subunit, directs the synthesis of large subunits in Escherichia coli. This provides a means for obtaining a preparation of
The properties of the tight and specific binding of 2-C-carboxy-d-arabinitol 1,5-bisphosphate (CABP), which occurs only to reaction sites of ribulose 1,5-bisphosphate carboxylase (Rubisco) that are activated by CO(2) and Mg(2+), were studied. With fully active purified spinach (Spinacia oleracea)
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is a hexadecamer of approximately 550 kDa in most organisms. Rotational-echo double-resonance (REDOR) and transfer-echo double-resonance (TEDOR) solid-state NMR were used to obtain the average internuclear distance between the 99%
