Chelatase-like Island integration determinant (iid) associated with genomic islands in completed microbial genomes.

aCDS number, % identity at protein level and genomic island integration position relative to the intact island integration determinant CDS META1_1797 of M. extorquens AM1.bCDS number, orientation relative to the upstream island integration determinant and % identity at protein level with the recombinase of strain DM4.cDR: direct repeat; PAL: palindrome; Rec: recombinase. Slashes indicate sequence overlap, > and M. loti, the two palindromic sequence pairs are only separated by three and four bases, respectively. Overlapping segments of direct repeat and palindromic sequences are indicated in bold or underlined (5��-end or 3��-end of the genomic island, respectively). Bases between square brackets indicate alternative bases in the corresponding motif.dGenome %GC content given in brackets.

a. 编码序列（CDS，Coding Sequence）编号、蛋白质序列一致性百分比，以及相对于黏滑甲基杆菌（M. extorquens AM1）完整基因组岛整合决定因子编码序列META1_1797的基因组岛整合位点。
b. 编码序列编号、相对于上游岛整合决定因子的方向，以及与DM4菌株重组酶的蛋白质序列一致性百分比。
c. DR：同向重复序列（direct repeat）；PAL：回文序列（palindrome）；Rec：重组酶（recombinase）。斜杠表示序列重叠，符号>及百脉根根瘤菌（M. loti）中，两组回文序列对分别仅相隔3个与4个碱基。同向重复序列与回文序列的重叠区段分别以粗体或下划线标注（分别对应基因组岛的5'端或3'端）。方括号内的碱基代表对应基序中的可变碱基。
d. 基因组GC含量以括号内数值标注。
