Apologies for duplicate posting. If you visit my IUPAC Nomenclature Web site (see below) site you will find I have recently added Basic Terminology of Stereochemistry (IUPAC Recommendations 1996) identical to the version published in Pure Appl. Chem. 68, 2193-2222 (1996). In addition I have added the 1995 IUPAC values for atomic weights published in Pure Appl. Chem., 1996, 68, 2339-2359. Some of the changes were added earlier last year but the details of all the changes and additions are now available. If you are interested in Enzyme Nomenclature I have added all of category EC 3.4 The Proteases. Details are provided of 270 enzymes which cleave proteins and peptides. Please note that the URL of this site was changed last November to that given below. For the moment the old address will work - but not for ever ! If you are interested in receiving direct information on changes to this data base send a message to g.p.moss@qmw.ac.uk requesting update information and giving your e-mail address and name. This mail list is only used by me for this purpose.
