Taking Shewanella and Geobacter as examples, this paper reviewed three kinds of possible mechanisms of microbial enzyme-catalyzed dissimilatory Fe reduction and its molecular regulation, i.e., direct contact between microbial cell and Fe oxides, siderrophores, and electron shuttling compounds. Many membrane-bound cytochrome proteins are involved in the dissimilatory Fe reduction, forming a complicated regulation network.

The 648 bp mitochondrial cytochrome c oxidase subunit I gene was examined in 8 species of raptors (5 species in Accipitridae, Falconiformes; 3 species in Strigidae, Strigiformes) by PCR with universal primers. 99 additional barcode sequences were downloaded to explore whether the DNA barcodes could distinguish between these species.

用DNA条形码通用引物扩增了我国8种猛禽（14只个体）的线粒体细胞色素c氧化酶亚基I基因，选取648 bp DNA条形码标准区域，结合99条猛禽条形码序列，探讨DNA条形码对猛禽的识别和鉴定。

Mutant libraries created by saturation mutagenesis of each single amino acid site D168, A225, K434 and E435 were screened to further improve the capability of cytochrome P450 BM-3(A74G/F87V/L188Q) mutant from Bacillus Megaterium which can hydroxylate indole into indigo. Results showed that D168, K434 and E435 are located at the functional domain of P450 BM-3 protein while A225 is sited at the unfunctional domain.

为了进一步获得具有更高活力的细胞色素P450 BM-3(F87V/A74G/L188Q)突变酶，利用饱和突变技术对该突变酶的4个氨基酸位点D168、A225、K434、E435分别进行单一的随机突变，通过对其羟基化吲哚生成靛蓝的催化性能表征，发现P450 BM-3氨基酸残基的168、434和435位均位于蛋白功能区域，而225位则位于非功能区域。
