查询词典 amino acid

In this paper, the cDNA sequence from Ampullaria crossean stomach named Dy1300 was obtained by RT-PCR firstly and cloned into vector pMD 18-T. Its ORF named SXYN contains 882bp nucleotide encoding a 294 amino-acid protein. The percentage of similarity of SXYN with the reported cellulase EGX gene sequence from Ampullaria crossean was 89.8%.

To realize the molecular compositions and bio-spinning mechanisms of spidroin in spider major ampullate, the molecular weight and amino acid compositions of spidrion solution were measured and compared with that of dragline silk. The molecular conformations and morphologies of spidroin and dragline silk in different spinning phases were determined by circular dichroism spectroscopy and laser Raman spectroscopy.
