6-carboxy-5,6,7,8-tetrahydropterin the key ring-contraction step involves a bridged intermediate rather than a ring-opening one. For the QueE-Mg2+ system, the elimination of ammonia is calculated to be rate limiting, determined by investigation at an atomistic level by using the combined quantum mechanics and molecular mechanics method Burkholderia multivorans 7-carboxy-7-carbaguanine + NH3
