RNA polymerase from E. coli does not function at 0ºC, whereas in vitro experiments determined that RNA polymerase from Pseudomonas syringae strain Lz4W functions at about 10%-15% of its optimum, which is 37ºC. Which of the following best explains the difference?

Since there is no distinction in the measure of the RNA polymerases yet rather their movement, the distinction lies in their structure and not their grouping. Adjustments are made to widen the states of endurance. Thus E. coli would not constrain it's endurance by restricting its development to hotter temperatures. Thus the appropriate response is "the RNA polymerase sub-units of the P. syringe strain most likely have additional adaptability with the goal that they can move all the more openly in colder temperatures".
