Codon Bias

The codon bias is said to be important in the comparison of orthologs, specifically inserting new genes into a model organism. The codon bias for the MT-CO1 geneis shown below [1,2]. All other orthologs of the gene can have their sequence analyzed based on the codon bias using Gene Infinity Codon Usage.

SMART Search

SMART was used to determine known domains found within the amino acid sequence of Cytochrome c Oxidase subunit 1. A total of 12 trans membrane domains were found (shown below) through the TMHMM Server v 2.0.

PROSITE Search

PROSITE was used to determine known domains found within the amino acid sequence of Cytochrome c Oxidase subunit 1. A Heme-copper oxidase catalytic subunit, copper B binding region signature domain (PS00077) was found from amino acids 236-291.

ProDom Search

ProDom was used to determine known domains found within the amino acid sequence of Cytochrome c Oxidase subunit 1. A large number of domains were found using 3 different algorithms (shown below). However, most "Submit Query" links were unusable, and did not yield further information of the domain. Those that did have active links were of little use, as they only aligned other sequences with the domain, rather than give the common function.
