4-Aminopyrimidines, ring

In the recent past, the author with collaborators established the presence of various tautomeric and ionization states of ThDP (Schemes 1 and 2). With the publication of the first high-resolution X-ray structures of ThDP enzymes,two issues were clarified for the first time (1) The conformation of the bound coenzyme (defining the dihedral angles formed by the thiazolium and 4 -aminopyrimidine rings with respect to the bridge methylene group was quite different (so-called V conformation) from that found and predicted for both free... [Pg.562]
