| Formate as an Inhibitor of Photosynthetic Electron Flow  | | | | Abstract
| The effects o f formate on the Hill reaction in isolated broken pea chloroplasts were in vestigated. Addition o f formate to chloroplasts has two distinct effects: I. basal electron flow can be stimulated 3-fold; 2. uncoupled electron flow is inhibited. The stim ulating effect is due to uncoupling by formate and appears instantaneous. M axim al inhibition by form ate is only observed after prolonged illumination. The inhibitory action o f form ate on electron flow can be relieved by bicarbonate *. | | | |

| Cyanoacrylate Inhibitors of the Hill Reaction III. Stereochemical and Electronic Aspects of Inhibitor Binding | | | | Abstract
| Ethoxyethyl 3-octylamino-2-cyanoacrylate and related com pounds in which the am ino group was replaced by N -C H 3, S, O and CH 2 were synthesized and their activity as inhibitors o f the Hill reaction in isolated pea chloroplasts determ ined. All com pounds show ed m oderate to high activity but there was no obvious correlation between activity and the electronic character o f the ester carbonyl group. The stereochemistry o f the various inhibitor m olecules was deduced from the PMR spectra and the possible influence o f stereochem istry on Hill inhibitory activity discussed. Replacement o f the olefinic proton in the 2-cyanoacrylates with a /?-alkyl substituent was examined and a specific relationship between the length o f the alkyl chain and activity was observed. | | | |
