Abstract

A number of pteridine derivatives stimulate photosynthetic phosphorylation in spinach chloroplasts. In general, tetrahydro or dihydro compounds are highly active, as is one aromatic, naturally occurring compound, biopterin. The physiological characteristics of this photosynthetic phosphorylation are the same as those described for phosphodoxin. A pteridine-containing fraction from spinach, with the same RF value as phosphodoxin, is also active.
