Abstract

The kinetics of growth, extracellular alpha-amylase formation and pool sizes of guanosine polyphosphates (p)ppGpp and adenosine phosphates (ATP and AMP) were determined during discontinuous cultivation of Bacillus subtilis 44. The results indicate a positive involvement of (p)ppGpp in the regulation of the expression of the alpha-amylase gene.

枯草芽孢杆菌胞外α -淀粉酶的形成与鸟苷多磷酸的关系。
研究了枯草芽孢杆菌44的生长动力学、胞外α -淀粉酶的形成和胞外α -淀粉酶的形成及胞外α -淀粉酶池大小。结果表明(p)ppGpp积极参与α -淀粉酶基因的表达调控。
