Yeast Malate Dehydrogenase: Enzyme Inactivation in Catabolite Repression [PDF]

European Journal of Biochemistry, 1967
The apparent inactivation of malate dehydrogenase activity in yeast following exposure to glucose has been studied. It was found to be prevented by inhibition of protein synthesis with cycloheximide, by addition of sodium azide, and by chilling the yeast

STUDIES ON REPRESSION OF THE HISTIDINE OPERON, II. THE ROLE OF THE FIRST ENZYME IN CONTROL OF THE HISTIDINE SYSTEM [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 1969
Recent studies on repression of the enzymes for histidine bio-synthesis in Salmonella typhimurium demonstrated that the kinetic pattern in which the enzymes become repressed is influenced by the state of the feedback-sensitive site of the first enzyme of

Phytochrome-Mediated Repression of Enzyme Synthesis (Lipoxygenase): A Threshold Phenomenon

Proceedings of the National Academy of Sciences of the United States of America, 1970
Synthesis of the enzyme lipoxygenase in the cotyledons of the mustard seedling (Sinapis alba L.) is controlled by phytochrome (P(fr)) through a threshold mechanism.

Transcriptional response of Methanosarcina acetivorans to repression of the energy-conserving methanophenazine: CoM-CoB heterodisulfide reductase enzyme HdrED [PDF]

Microbiology Spectrum
Methane-producing archaea are key organisms in the anaerobic carbon cycle. These organisms, also called methanogens, grow by converting substrate to methane gas in a process called methanogenesis.

REPRESSION-DEPENDENT ALTERATION OF AN ARGININE ENZYME IN Escherichia coli [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 1969
Treatment of susceptible Escherichia coli K12 derivatives with 0.4 M Mg(++) at 37 degrees , potentiated by L-arginine or L-canavanine, leads to alteration of acetylornithine delta-transaminase. The alteration, obtained in the absence of protein synthesis

Glucose Catabolite Repression Participates in the Regulation of Sialidase Biosynthesis by Antarctic Strain Penicillium griseofulvum P29 [PDF]

Journal of Fungi
Sialidases (neuraminidases) catalyze the removal of terminal sialic acid residues from glycoproteins. Novel enzymes from non-clinical isolates are of increasing interest regarding their application in the food and pharmaceutical industry.

Repression of the SUMO-conjugating enzyme UBC9 is associated with lowered double minutes and reduced tumor progression [PDF]

Cancer Biology & Therapy
Double minutes (DMs), extrachromosomal gene fragments found within certain tumors, have been noted to carry onco- and drug resistance genes contributing to tumor pathogenesis and progression.
