Characterization of the Complete Mitochondrial Genome ofDerived from Cows in Shanghai, China.

Abstract

A study was conducted to reveal the characterization of the complete mitochondrial genome ofderived from cows in Shanghai, China. Results indicated that the completegenome ofwas 14,288 bp and contained 12 protein-coding genes (,,,, and), 22 transfer RNA genes, and two ribosomal RNA genes (l-rRNA and s-rRNA). The overall A + T content of thegenome was 63.83%, and the nucleotide composition was A (19.83%), C (9.75%), G (26.43%), and T (44.00%). A total of 3284 amino acids were encoded by currentisolategenome, TTT (Phe) (9.84%) and TTG (Leu) (7.73%) codon were the most frequent amino acids, whereas the ACC (Thr) (0.06%), GCC (Ala) (0.09%), CTC (Leu) (0.09%), and AAC (Asn) (0.09%) codon were the least frequent ones. At the third codon position ofprotein genes, T (50.82%) was observed most frequently and C (5.85%) was the least one. The current results can contribute to epidemiology diagnosis, molecular identification, taxonomy, genetic, and drug development researches about this parasite species in cattle.
