The length of this phytase gene is1506bp interrupted once by an intron of 102bp in the 5 “ part of the gene , this intron contains donor sequence - gtatgc , lariat sequence - gctgac and acceptor sequence - cag which are typically conserved sequence of the intron of fungal phytase gene . this gene encodes a peptide of 467amino acid residues with molecular weight of 51 . 37kda , containing 13 potential n - glycosylation sites and a signal peptide sequence made up of 19 amino acid residues at n teminal of the peptide 核苷酸序列分析表明, pcr擴增產物中包含有完整的phya基因,該基因全長1506bp ,其中包含一段長102bp的內含子,該內含子具有真菌植酸酶基因內含子的特征保守序列: donor序列? gtatgc , lariat序列? gctgac及acceptor序列? cag 。該基因編碼467個氨基酸,理論分子量為51 . 37kda ,其上有13個潛在的n -糖基化位點, n端19個氨基酸為信號肽序列,植酸酶活性位點序列( crvtfaqvlsrhgaryptdskgk )位于氨基酸序列的+ 71 + 93 。
