皇家浆(RJ)是一种粘稠的乳状物质,由蜜蜂的下咽腺和下颌腺分泌。RJ的主要蛋白质称为apalbumins或主要皇家果冻蛋白(MRJPs),具有多种生物学功能。Apalbumin 1是RJ最丰富的糖蛋白。本研究利用新建立的Bac-to-Bac/BmNPV杆状病毒表达系统(BES)构建了中华蜜蜂Bacmid-apalbumin 1基因。该方法使我们能够获得重组A.用BmNPV bacmid系统从家蚕幼虫血淋巴中分离出中华蚕(Acc)apalbumin 1(rAccapalbumin 1)。然后通过Ni-NTA旋转柱纯化r Accapalbumin 1,并进行十二烷基硫酸钠-聚丙烯酰胺凝胶电泳和Western印迹。然后获得具有良好溶解性的55 kDa蛋白。从胰蛋白酶产生的r Accapalbumin 1中鉴定出肽Ile-Phe。已报道这种肽具有抗高血压能力。因此,我们的研究结果在生物医学研究中具有潜在的应用,并为apalbumins的研究开辟了新的前景。
Royal jelly (RJ) is a thick, milky material produced by both the hypopharyngeal and the mandibular glands of nurse honeybees. The main proteins of RJ, named apalbumins or major royal jelly proteins (MRJPs), have multiple biological functions. Apalbumin1 is the most abundant glycoprotein of RJ. In this study, Bacmid- apalbumin1 was constructed for Apis cerana cerana using the newly established Bac-to-Bac/BmNPV baculovirus expression system (BES). This procedure allowed us to obtain the recombinant A. cerana cerana ( Acc) apalbumin1 (r Accapalbumin1) from the hemolymph of silkworm larvae through the BmNPV bacmid system, 96 h postinfection. The r Accapalbumin1 was then purified by Ni-NTA spin columns and subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting. A 55 kDa protein with good solubility was then obtained. The peptide Ile-Phe was identified from trypsin production of r Accapalbumin1. Such a peptide has been reported to have an antihypertensive ability. Our results have therefore potential applications in biomedical research and open new perspectives for the study of apalbumins.
