Abstract

Amines are a group of highly important compounds of biological importance; they are known promoters of cell growth, can complex with nucleic acids and can stimulate DNA-primed RNA polymerase activity. Spermine, a polyamine abundantly present in the secretions of the male accessory sex organs, has received no functional attributes till date. This study had been a pioneer attempt to validate the hypothesis of a metalloenzyme activity modulation by spermine and implicit correlations have been drawn.

摘要

胺类是一类具有高度生物学重要性的化合物;它们是已知的细胞生长促进剂,能与核酸结合,并能刺激以DNA为引物的RNA聚合酶活性。精胺是一种大量存在于雄性附属生殖器官分泌物中的多胺,迄今为止尚未发现其功能特性。本研究首次尝试验证精胺对金属酶活性的调节假说,并得出了潜在的相关性。
