蜂王浆中一种有抗菌活性的小肽

AN ACTIVE PEPTIDE INHIBITING BACTERIA IN THE ROYAL JELLY OF HONEY BEE

用分子筛柱层析的方法，从蜂王浆的水溶性物质中分离出一种新的活性肽，对革兰氏阳性菌有明显的抑制作用，其分子量约为２．３ｋＤ，含８种氨基酸，其中甘氨酸占３３％，表明它是一种富含甘氨酸的小肽。

A new active peptide which can inhibit the grampositive bacteria strongly,is separated from the soluble components of royal jelly of honey bee (APtSmellifera ligustica) with gel filtration. The molecular weight of the peptide is about2.3kD. TIs peptide is composed of 8 amino acids, in which glycine accounts for 33per cent.
