Narrative:

Wake turbulence during landing causes multiple EICAS error messages. We were cleared for a visual approach to runway 16R at sea; following a 737. The captain was the pilot flying. On final; with the auto pilot off; we encountered wake turbulence that rocked the plane back and forth pretty good. This was soon followed by several EICAS messages. The messages that I recall seeing included: stall prot fail; wshr detect fail; aoa limit fail; and at fail. I think there may have been more messages displayed but this is all I recall as I write this report. I asked the captain if we should add a few knots to our vapp speed and he said we should go around and sort this out. Inside the FAF and fully configured; we executed a go-around. Once we were back with approach; the captain transferred the flying and radio responsibility to me and he went through the QRH. From the QRH we determined what our new approach speed should be as a result of the failures. This new approach was higher then what we had originally planned; so it was good thing we checked. We had lost all of our stall protection and wind shear detection. He notified dispatch; the flight attendants; and ATC of our situation and requested 28L. He also gave an update to the passengers. Once we were ready to commence a new approach he took over the flying duties and we landed without incident. After landing the EICAS messages that we previously displayed went away and were replaced with ads 1 & 3 failure message.
