Narrative:

Inbound to iah, we were cleared by ATC to turn off the arrival at akeem intersection to a 260 degree heading for vectors to final. We missed the turn and were then called by iah approach to turn to a heading of 280 degrees. There was no known conflicts with any traffic. ATC made no comments. I think this was caused by the distraction of high cockpit workload (approach checklist, etc) and I firmly believe that fatigue was a factor due to the late hour and a long day. To possibly prevent this, I try to 'build' a point in the FMS ahead of time when there is a known turn on an arrival (such as in dfw or mem). We were close in, busy and descending when this instruction was issued so I did not attempt to build the turn.
