Carboxylation of phenylphosphate by phenol carboxylase, an enzyme system of anaerobic phenol metabolism.

Lack, A, Fuchs, G

Several lines of evidence indicate that the first step in the anaerobic metabolism of phenol is phenol carboxylation to 4-hydroxybenzoate; this reaction is considered a biological Kolbe-Schmitt...

Anaerobic toluene oxidation to benzyl alcohol and benzaldehyde in a denitrifying Pseudomonas strain.

Altenschmidt, U, Fuchs, G

Oxidoreductases Involved in Cell Carbon Synthesis of Methanobacterium thermoautotrophicum

Zeikus, J. G., Fuchs, G., Kenealy, W., Thauer, R. K.

Cell-free extracts of Methanobacterium thermoautotrophicum were found to contain high activities of the following oxidoreductases (at 60°C): pyruvate dehydrogenase (coenzyme A acetylating), 275...

Reduced Ferredoxin: CO2 Oxidoreductase from Clostridium pasteurianum: Its Role in Formate Metabolism

Thauer, R. K., Fuchs, G., Jungermann, K.

The activity of reduced ferredoxin: CO2 oxidoreductase in Clostridium pasteurianum was correlated with the accumulation of formate in the growth medium. The data indicate that the in vivo function of...

Pathogenesis of Shigella diarrhea: rabbit intestinal cell microvillus membrane binding site for Shigella toxin.

Fuchs, G, Mobassaleh, M, Donohue-Rolfe, A, Montgomery, R K, Grand, R J, Keusch, G T
