The reaction of the amino groups of bovine serum albumin (BSA) with diacetylcycloserine (I) at pH 7.2-9.0 proceeded with both acylation by the diacetyl-beta-aminooxy-D-alanyl (DAA) group and acetylation. The number of DAA groups was determined by their conversion to cycloserine (III) which can be accurately measured in micromolar amounts. The method was developed using the model compound diacetyl-beta-aminooxy-D-alanine butyl amide (II) which was converted to beta-aminooxy-D-alanine butyl amide (IV) by methanolysis and then to cycloserine by basic ring-closure of IV. Calculations using results obtained by this method combined with the experimentally determined number of free amino groups in the modified BSA indicated that the reaction of excess I with BSA effected the acetylation of about 35 and the acylation with DAA groups of about 22 of the 59 amino groups. These findings were supported by experiments demonstrating that the amount of acetic acid formed by hydrolysis of the modified BSA was approximately that predicted from the results of the cycloserine analyses.
