The effect of different adenine-containing compounds on the NADP-/NAD-glutamate dehydrogenase (GDH) ratio was studied as a function of yeast-mycelium transition in Benjaminiella poitrasii. Under in vivo conditions, at a 5.0 mM concentration, cyclic AMP (cAMP) and dibutyryl cAMP maintained the cells in the yeast form for up to 7 and 5 h, respectively, and this was reflected in the patterns of GDH ratios observed. In vitro studies of phosphorylation and dephosphorylation have also been carried out, and the results suggest a possible correlation between cAMP, the GDH ratio, and cell form in B. poitrasii.
研究了不同含腺嘌呤化合物对本杰明氏菌酵母-菌丝体转变过程中NADP⁻/NAD-谷氨酸脱氢酶(GDH)比率的影响。在体内条件下,浓度为5.0 mM时,环磷酸腺苷(cAMP)和二丁酰cAMP分别使细胞保持酵母形态长达7小时和5小时,这反映在观察到的GDH比率模式中。还进行了磷酸化和去磷酸化的体外研究,结果表明cAMP、GDH比率和本杰明氏菌细胞形态之间可能存在相关性。
