Question

At physiological ph, what will be the principal interactions between arg681 and cys683?

Answer 1

Answer:

Since the interaction between Arg681 and Cys683 is intra-subunit, the two residues must be located on the same chain.

Explanation:

What is intra-subunit interaction?

The bacterial condensin is an SMC-like protein complex called MukBEF. It is most likely that it compacts DNA through a DNA loop-extrusion mechanism that is ATP hydrolysis dependent, as has been shown for the yeast SMC proteins condensin and cohesin. Despite suppressing MukB ATPase activity, MukB also interacts with the ParC subunit of the cellular chromosomal decatenase topoisomerase IV, which is necessary for normal chromosome condensation and segregation in E. coli. In our investigation of the MukBEF ATPase function, we used protein-protein crosslinking and site-specific mutagenesis to pinpoint connections between and within subunits.
