concerted feedback inhibition of the aspartokinase of rhodospirillum tenue by threonine and methionine: a novel pattern.the presence of a single aspartokinase was demonstrated in rhodospirillum tenue. the enzyme has been purified about 60-fold. no physical association exists in this species between aspartokinase and homoserine dehydrogenase. the general properties of the enzyme are described. inhibition by l-lysine, by l-threonine, and concerted inhibition by these two end products are regulatory characters which have also been found in many other species. in r. tenue, aspartokinase is also subject to a hitherto ...19725079065
ribulose diphosphate carboxylase from autotrophic microorganisms.thiobacillus denitrificans was grown anaerobically with nitrate as an acceptor in both sterile and nonsterile media. ribulose diphosphate carboxylase was stable throughout the exponential growth phase and declined slowly only after cells reached the stationary phase. reversible inactivation of the carboxylase occurred in extracts as a result of bicarbonate omission. the enzyme was purified 32-fold with excellent recovery of a preparation which was 50 to 60% pure by the criterion of polyacrylamid ...19724623310
lifetime of the excited state in vivo. ii. bacteriochlorophyll in photosynthetic bacteria at room temperature.lifetime of the excited state (tau) of bacteriochlorophyll (bchl) in photosynthetic bacteria, measured with a mode-locked argon laser (oscillating at 488 nm; mode locked at 56 mhz) as light source, ranged from 0.3 to 2.5 nsec. these tau values are reported with a precision of +/-0.1 nsec. the value of tau at high exciting light intensity (i) was two to three times that at low intensity. for young cultures of green bacterium chloropseudomonas ethylicum, tau ranged from 0.5 (low i) to 1.0 nsec (hi ...19724624833
