The effects of chemical modifications on the reconstitution, activity, and stability of clostridial ferredoxin.
Native ferredoxin isolated from Clostridium acidi-urici cannot be acetylated and is not digested by carboxypeptidase A. However, apoferredoxin, free of iron and sulfide, can be acetplated and the COOH-terminal alanine and glutamine residues are quantitatively removed by carboxypeptidase A. Ferredoxin derivatives can be reconstituted from both modified proteins. The following derivatives were al...
متن کاملInactivation of clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase by sodium nitrite.
Clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase activity was investigated after in vitro or in vivo treatment with sodium nitrite. In vitro treatment of commercially available Clostridium pasteurianum ferredoxin with sodium nitrite inhibited ferredoxin activity. Inhibition of ferredoxin activity increased with increasing levels of sodium nitrite. Ferredoxin was isolated from norma...

to detect hybrid particles. Although the RNA of dependent virus often replicated to a level about 10 per cent of that of supporting virus,' maturation of intact dependent virus within heterologous capsid was much less efficient. This could be due to a better fit between capsomeres and homologous RNA or it could be due to a spatial relationship between capsomere protein synthesis and the viral R...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
