  1. Methods : an artificial gene for fl extracellular domain cdna was synthesized by using favored genetic codons of pichia pastroris. by inserting human fl extracellular domain cdna coding 156 amino acid resi dues into pichia pastoris expression vector ppic9k containing aox1 promoter and the sequences of alpha secreting signal peptides, a recombinant expression plasmid ppic9k - fl was constructed, and integrated into the alcohol oxidase region of the host genome

    為了提高外源基因的表達量，我們根據畢赤氏酵母偏愛密碼子人工合成了編碼fl胞外區156個氨基酸的cdna序列，目的序列被定向克隆到酵母分泌型表達載體ppic9k質粒上，構建ppic9k - fl表達質粒。
  2. Proteolytic enzymes catalyze oligomerization of the. alpha. - hydroxy carboxylic acid and. alpha. - amino acid

    蛋白水解酶催化-羥基羧酸和-氨基酸的低聚化。
  3. In a preferred embodiment, a. alpha. - hydroxy carboxylic acid with a specific chiral configuration is linked by an amide linkage to a. alpha. - amino acid specific with a specific chiral configuration or linked by an amide linkage to a peptide made up of. alpha. - amino acid monomers having identical chiral configurations

    主要體現在，含有特定結構的-羥基羧酸與一個含特定結構的-氨基酸以氨基聯接特異結合，或與一個有相同結構的，由-氨基酸單體組成的肽以氨基聯接相連。
  4. The nucleotide sequence similarity of alpha - amylase gene of bombyx mori and bombyx mandarina is 90 % and the putative amino acid sequence similarity is as high as 98 %
