Operate to = able to?

Hi.
"Others contend that for a factor to be considered protective, it must operate in the presence of an existing risk factor to reduce the negative impact of the risk factor. "

Or, in other words:
"Others contend that for a factor to be considered protective, in the presence of an existing risk factor, it must operate to reduce the negative impact of the risk factor."

Does 'oprate to reduce' mean 'able to reduce' here?

Well, something that is operating is in the process of achieving a desired effect. Something that is able just has the ability to do something, but is not yet doing it. However, in your sentence it says it "must operate to reduce" something. This is talking in theory, so then you could change it out to "must be able to reduce" because you are talking about possibility and neither one is current
