The intracellular level of S-adenosylmethionine increased as the yeast-phase cells of Mucor racemosus were induced to convert to hyphae. This increase correlated well with time course of the conversion in cell type and was independent of the metabolic changes caused by the shift to aerobic conditions. There was no significant change in the intracellular level of spermidine, a polyamine synthesized from putrescine and the propylamine group of S-adenosylmethionine. Spermine was not detected. An examination of protein methylation revealed an increase in the methylation of total protein during the shift in cell type and possible qualitative as well as quantitative changes in specific base proteins.
当总状毛霉的酵母相细胞被诱导转化为菌丝时，细胞内S-腺苷甲硫氨酸水平升高。这种升高与细胞类型转化的时间进程密切相关，且与向需氧条件转变所引起的代谢变化无关。由腐胺和S-腺苷甲硫氨酸的丙胺基团合成的多胺亚精胺，其细胞内水平没有显著变化。未检测到精胺。蛋白质甲基化检查显示，在细胞类型转变过程中，总蛋白质的甲基化增加，特定碱性蛋白质可能存在定性和定量变化。
