古生代rRNA基因(RDNA)中有超过50个内含子被报道,其中一个子集嵌套了可能的归巢内切酶(Hease)基因。在这里,我们报道了一种新的古生菌LAGLIDADG型Hease,I-ApeKI[更正],它由Pernix Aeropyrum K1的16S rDNA中的ApeK1.S908内含子编码。I-ApeKI[更正]由222个氨基酸组成,含有两个LAGLIDADG样序列。它识别20bp的非回文序列5‘-GCAAGGCTGAAAC向下箭头TTAAAGG,并切割目标DNA以产生突出的四核苷酸3’端。在裂解反应中,可以用Mn2+或Co2+替代Mg2+作为辅因子。在最小识别位点内的20个碱基中,有7个碱基是切割所必需的,它们位于切割位点的近端。
Over 50 introns have been reported in archaeal rRNA genes (rDNAs), a subset of which nests putative homing endonuclease (HEase) genes. Here, we report the identification and characterization of a novel archaeal LAGLIDADG-type HEase, I-ApeKI [corrected], encoded by the ApeK1.S908 intron within the 16S rDNA of Aeropyrum pernix K1. I-ApeKI [corrected] consists of 222 amino acids and harbors two LAGLIDADG-like sequences. It recognizes the 20 bp non-palindromic sequence 5'-GCAAGGCTGAAAC downward arrowTTAAAGG and cleaves target DNA to produce protruding tetranucleotide 3' ends. Either Mn2+ or Co2+ can be substituted for Mg2+ as a cofactor in the cleavage reaction. Of the 20 bases within the minimal recognition site, 7 are essential for cleavage and are located at positions proximal to the cleavage sites.
