" the more surface area we have around the catalytic sites , the better it works and the more power output we can have , " hockaday notes 霍克蒂注意到: “催化部位的表面积越大,它就能更好地作用,而我们就能有更大的功率输出。 ”
Because the catalytic site of a - aldc has not been certified and the catalytic mechanism has to be also further proved , it is difficult to enhance the enzyme activity in low temperature by the rational design 由于- aldc的活性部位尚未完全确定,催化机理也需进一步证实,在这种条件下通过酶的合理化设计来提高酶在低温下的活力有一定困难。
Moreover , asp immediately preceding the active site ser is necessary for proper folding of the catalytic site . the human clsp cdna corresponded to unigene cluster hs . 415792 located on human chromosome 12pl3 . 31 . nucleotide sequence alignment of clsp and this sequence enabled us to demonstrate the genomic structure of the clsp gene with appropriate exon - intron boundaries , which contained 6 exons and 5 introns Clsp在造血细胞系的表达较为特殊,不表达于淋巴瘤细胞系,只表达于单核髓系白血病细胞系,如慢性髓系白血病k一562 、髓系单核白血病thp一1 、前髓系白血病hl一60和b4 ,以及急性髓系白血病kg一1细胞系,其中thp一1细胞系经lps刺激后clsp表达水平亦呈上升趋势。
