Abstract
  1. When the diet of sheep is supplemented by the abomasal infusion of sulphur-containing amino acids or casein, a special group of proteins, with a very high content of sulphur (about 8.3%), is incorporated into the high-sulphur proteins of wool. These special proteins cannot be detected in control wool from the same sheep. 2. This is a naturally occurring process, as these special proteins are found in wool from sheep on a high level of nutrition under ordinary conditions of feeding, and in wool of an inherently high sulphur content. 3. This represents a control mechanism in protein synthesis that has not previously been observed, and may be further evidence that the high-sulphur proteins of wool are produced by an unusual synthetic route.
摘要
  1. 当给绵羊的日粮通过皱胃灌注含硫氨基酸或酪蛋白进行补充时,一组特殊的蛋白质会被整合到羊毛的高硫蛋白质中,这些蛋白质的硫含量非常高(约8.3%)。在同一绵羊的对照羊毛中无法检测到这些特殊蛋白质。2. 这是一个自然发生的过程,因为在普通饲养条件下营养水平较高的绵羊的羊毛中以及硫含量天生就高的羊毛中都能发现这些特殊蛋白质。3. 这代表了一种以前未被观察到的蛋白质合成控制机制,可能进一步证明羊毛的高硫蛋白质是通过一条不寻常的合成途径产生的。
