This page will be specifically focusing on the structure and overall function of the 6RX4 ''bd'' oxidase in [https://en.wikipedia.org/wiki/Escherichia_coli ''E. coli'']. 6RX4 is a part of the long(L) quinol-binding domain subfamily that terminal oxidases are classified into. The L-subfamily of ''bd'' oxidases are responsible for the survival of acute infectious diseases such as ''E. coli'' and [http://www.example.com salmonella]. The 6RX4's three <scene name='83/832931/Heme/4'>heme</scene> groups, its periplasmically exposed <scene name='83/832924/Q_loop/3'>Q-loop</scene>, and <scene name='83/832942/Four_subunits_labelled_6rx4/2'>four protein subunits</scene> will be of primary focus when identifying the relationship between structure and function.
