Comparative biochemistry of CO2 fixation and the evolution of autotrophy [PDF]

open access: yes, 2010
Carbon dioxide fixation is a polyphyletic trait that has evolved in widely separated prokaryotic branches. The three principal CO2-assimilation pathways are (i) the reductive pentose-phosphate cycle, i. e.

Syntheses and characterization of vitamin B12-Pt(II) conjugates and their adenosylation in an enzymatic assay [PDF]

open access: yes, 2018
Aiming at the use of vitamin B12 as a drug delivery carrier for cytotoxic agents, we have reacted vitaminB12 with trans-[PtCl(NH3)2(H2O)]+, [PtCl3(NH3)]− and [PtCl4]2−. These Pt(II) precursors coordinated directly to the Co(III)-bound cyanide, giving the
