We present a case of Gerbode type defect (left ventricular to right atrial communication) discovered in a 52 year-old man with atrial and ventricular septal defects. The patient was diagnosed using two-dimensional colour Doppler and transoesophageal echocardiography. We describe the echocardiographic features and review the anatomical consequences of such(More)
The conversion of L-lysine to L-beta-lysine is catalyzed by lysine 2,3-aminomutase. The reaction involves the interchange of the 2-amino group of lysine with a hydrogen at carbon 3. As such the reaction is formally analogous to adenosylcobalamin-dependent rearrangements. However, the enzyme does not contain and is not activated by this coenzyme. Instead it(More)
Epimers of [gamma-17O]adenosine 5'-O-(3-thiotriphosphate) ([gamma-17O]ATP gamma S) have been used to determine the stereochemistry of Mn2+ coordination to the terminal thiophosphoryl group in complexes of pyruvate kinase, oxalate, ATP gamma S, and Mg2+, Zn2+, Co2+, or Cd2+. The complex of pyruvate kinase with oxalate and ATP binds 2 equiv of divalent cation(More)
