The AZ_95-228, AZ_100-228 and AZ_95-176 peptides had IC50 values comparable to that of AZ_WT and formed AZ-ODC complexes with Kd, AZ-ODC values of 1.5 , 5.3 and 5.6 µM, respectively.
Our data also indicate that AZI can rescue AZ peptide-inhibited ODC enzyme activity and that it can bind to AZ peptides with a higher affinity than ODC.
