Col A when present in an <i>E. coli</i> cell is able to affect macromolecular synthesis throughout the cell, affecting many of the processes in the cell. One such affected system is nucleic acid synthesis; it is halted very soon after Col A is added to the system<ref>PMID:4905544 </ref>. | Col A when present in an <i>E. coli</i> cell is able to affect macromolecular synthesis throughout the cell, affecting many of the processes in the cell.

The structure determination of the C-terminal domain of protein was done by Dr. Parker and colleagues<ref> PMID:2909895 </ref><ref> PMID:1373773 </ref>. It enabled to better understand the stability of hydrophobic pockets, the energy transfer among the three tryptophan residue in that domain, and the creation of double-cysteine mutants to understand the transition from soluble to membrane associated protein<ref> PMID:8663026 </ref><ref> PMID:7849033 </ref><ref> PMID:7716161 </ref>. | |||
