Abstract

Heat-induced structural transitions of bacteriophage T4 ghosts have been studied using differential scanning microcalorimetry and electron microscopy. The tail reorganization process is not an exothermic one. It is shown to correlate well with a heat absorption peak at maximum of 70 degrees C, but the sheath contraction and the hexagon -to-star base-plate transition themselves appear to proceed without any significant changes in enthalpy.

摘要

利用差示扫描量热法和电子显微镜研究了噬菌体T4幽灵颗粒的热诱导结构转变。尾部重组过程不是一个放热过程。结果表明,它与70℃时的一个最大吸热熔解峰密切相关,但鞘收缩和六边形到星形的基板转变本身似乎是在没有任何明显焓变的情况下进行的。
