49t x 11-36 will give you a very similar range to a 50/34 11-25 road setup.
If you don't need as high a high gear, which you likely don't for commuting, you could switch to 48 x 12-36 or even lower.

if you already have a standard 53/39 setup i would just use the 39 as my front chainring. 39/11 is a decently high gear.
