My turn line varies a lot by opponent, but we should generally be looking to get stacks in here, or as close to it as we can by the river. There's two possible lines I like.
For my usual line, you have $22.51 behind in a $4.85 pot. If we pot the turn, we'll have $17.66 behind a $14.55 pot on the river, so we're going to have to over bet somewhere to get stacks in. Thus I probably make the turn bet around $4.25 and just shove the rest in on the river.
However, since this board is so dry, and you have three of the aces locked up, you can consider an alternate line of inducing a bluff/value bet from worse if your opponent is very aggressive. Check back the turn, hoping to shove over any bet he makes on the river. So if your opponent is calling the flop with a hand like QJ that can't stand a turn bet, it gives him an opportunity to turn that into a bluff. Look for a low fold to c-bet percentage and a high aggression factor if you're going to try this.
