Valine an amino acid synthesized from pyruvate . it is broken down to yield succinyl coa 纈氨酸:由丙酮酸合成的氨基酸。可分解產(chǎn)生乙酰輔酶a 。
Two positive clones were sequenced , and the results showed that its nuclcotidc sequence includes an open reading segment which codes for a 45 - amino acids protein and three endonuclcase sites which arc1 bgii , bamh i and bgi ii , this protein was identified as metallothionein based on its characteristic described above and its similarity ( 85 % ) to the mtn gene of drosophila : the 10 cysteine residues present occur in five pairs of cys - x - cys , x is serine , valine , ilistidine or lysine 結(jié)果顯示:擴(kuò)增的cdna片段長(zhǎng)度為289bp ,其中含有一個(gè)編碼45個(gè)氨基酸的開(kāi)放閱讀框,閱讀框所編碼的氨基酸中含有10個(gè)半胱氨酸,且在序列中均排列成cys - x - cys ,其中x為ser 、 val 、 his或lys 。這些特征說(shuō)明擴(kuò)增的基因片段為家蠅mt基因序列的一部分。此基因序列片段與果蠅mtn基因序列的同源性達(dá)到85 . 0 ,擴(kuò)增的基因序列中含有三個(gè)內(nèi)切酶位點(diǎn)bg 、 bam和bg ,這一點(diǎn)也和果蠅mtn基因十分相似。
