Narrative:

While on a 5 mile final to runway xx in ZZZ; we noticed previously identified traffic on a left downwind leg starting what looked like a turn to a base leg. Unsure of his intentions; we asked the aircraft; at which point they informed us they would be out of our way by the time we got there. We responded by saying that would not work; and requested they do a 360 degree turn to fall in behind us. They responded by saying 'ok; you're in sight.' at this point the aircraft began a turn as we expected; however we believe they shot a low approach in the process; but it was difficult see. Once on short final; we saw them again making a climbing left crosswind turn. Our aircraft then crossed the threshold; and encountered wake turbulence just prior to the left main wheel touching the ground. This caused the aircraft to lose lift suddenly; and drift left of the centerline. The first officer initiated a go-around. After the go-around we completed required checklists; I notified the flight attendant [and] passengers; and we landed uneventfully.
