propeptide 中文意思是什麼
propeptide
解釋
前肽[有時特指前膠原各肽鏈的兩端的肽段，也可泛指肽的前體-
The gene contains an open reading frame of 1149 nucleotides ( named ap gene, encoding 383 amino acids ), which contains a signal peptide consisting of 29 residues and a propeptide of 79 residues
該片段全長1588bp ，包括一個1152bp的編碼區序列，編碼全長為383個氨基酸殘基的蛋白質。根據軟體分析與同源性比較推測，該蛋白質含有由29個氨基酸殘基組成的信號膚， 79個氨基酸殘基組成的前膚。 -
The cdna sequence with 789 bp encodes an uncompleted open reading frame ( orf ) of 263 amino acids, which included a signal peptide of 18 amino acids, a proposed propeptide of 171 amino acids, a partial mature protein of 74 amino acids. the sequences of signal peptide and propeptide are very similar to ones from wannan agkistrodon acutus reported by fan chunyan, but it only contains partial amino acids of mature protein. the 800 bp is likely to be a part of gene encoding metalloproteinase agkistrodon acutus from guangxi province
結論： 600bp產物和已報道的皖南五步蛇纖溶酶金屬蛋白酶氨基酸序列相比較，有90 . 6 %的同源性； 800bp產物中信號肽及前肽和已報道的皖南五步蛇金屬蛋白酶很相似，同源性為97 . 9 % ，但僅含有部分金屬蛋白酶成熟肽的氨基酸序列，推測此片段為廣< wp = 6 >西五步蛇金屬蛋白酶原基因的一部分。
