Abstract:
We present the complete mitochondrial genome of Protonibea diacanthus in this study. The mitochondrial genome is 16,535 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. All of them are encoded on the heavy strand except ND6 and 8 tRNA genes on the light strand. The nucleotide compositions of the light strand are 31.09% of G, 27.54% of T, 25.34% of A and 16.03% of C. All the protein-coding genes start with ATG initiation codon except ATP6 with GTG, and 5 types of inferred termination codons are AGA (COXI and COXII), T (ND3, ND4, Cytb), TA (ND2, COXIII and ATP6), TAA (ND1, ATP8 and ND4L) and TAG (DN5 and ND6). There are 14 intergenic spacers and 7 gene overlaps. The tandem repeat sequence is observed in 12S-rRNA, 16S-rRNA, tRNA(Trp), tRNA(Ala), COXIII, ND4L and ND4 genes. Gene arrangement and distribution are consistent with the typical vertebrates.

Porin Insertion in the Outer Mitochondrial Membrane
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...
