[The inhibition of translation in Bacillus subtilis via the repression by the secreted enzyme of its synthesis]. / Ingibirovanie transliatsii u Bacillus subtilis pri repressii sekretirovannym fermentom ego sinteza.

It has been shown that inhibition of Bacillus subtilis alpha-amylase formation by the level of the active enzyme in the cultural medium leads to the decrease of translation accompanied by reduction of level of [14C] valin transport into the cells.

[Localization of secreted enzyme-induced repression of its synthesis by the cells]. / Lokalizatsiia repressii sekretirovannym fermentom ego sinteza kletkami.

It was shown that under conditions of regulation of secreted enzyme synthesis by its concentration in microorganisms, the repression of synthesis of the enzyme protein polypeptide chain and the concomitant partial repression of labelled amino acid transport into the cells occur. The regulatory effect can be exerted in the absence of transcription as well. These effects are not realized at the post-transcription or post-translation levels.
