Photorespiration Redesigned

Biochemical dissection of photorespiration.

Progress has been made in the understanding of photorespiration and related proteins (Rubisco, glycolate oxidase and glycine decarboxylase) in the context of recent structural information. Numerous shuttles exist to support transamination, ammonia refixation and the supply or export of reductants generated or consumed (via malate-oxaloacetate shuttles) in the photorespiratory pathway. A porin-l...

Measurement of photorespiration in algae.

The rates of true and apparent photosynthesis of two unicellular green algae, one diatom and four blue-green algae were measured in buffer at pH 8.0 at subsaturating concentrations of dissolved inorganic carbon (13-27 micromolar). Initial rates of depletion from the medium of inorganic carbon and (14)C activity caused by the algae in a closed system were measured by gas chromatography and by li...

GGobi: XGobi Redesigned and Extended

GGobi is a direct descendant of XGobi, with multiple plotting windows, a color lookup table manager, an XML (Extended Markup Language) file format for data, and other changes. Perhaps the biggest change is that GGobi can be embedded in other software and controlled using an API (Application Programming Interface). This design has been developed and tested in partnership with R. When GGobi is us...

Recent developments in photorespiration research.

Photorespiration is the light-dependent release of CO(2) initiated by Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) during oxygenic photosynthesis. It occurs during the biochemical reactions of the photorespiratory C(2) cycle, which is an ancillary metabolic process that allows photosynthesis to occur in oxygen-containing environments. Recent research has identified the genes for ma...
