Abstract This article aims to investigate the identity of Socrates, compiler AP 14.1-64 (arithmetic problems and riddles). Leaving aside traditional, but very uncertain, identification with Socrates epigrammatist (D.L. 2.47), it is shown that chronological conjecture by Carcopino 1926 (late 1st century BC -2nd AD ) no longer holds. A wider time frame established (1st-4th centuries ), although e...
We have prepared a site-specific mutant of human carbonic anhydrase (HCA) II with histidine residues at positions 7 and 64 in the active site cavity. Using a different isozyme, we have placed histidine residues in HCA III at positions 64 and 67 and in another mutant at positions 64 and 7. Each of these histidine residues can act as a proton transfer group in catalysis when it is the only nonlig...
