| Abstract: | Two distinct muconate cycloisomerases are involved in the degradation of aniline and 3-chloroaniline (3-CA) proceeding via the ortho-cleavage pathways in Pseudomonas acidovorans CA28. After partial purification of these two enzymes kinetic investigations resulted in a clear differentiation of aniline-derived muconate cycloisomerase (MC) and 3-CA-derived chloromuconate cycloisomerase (CMC). A further result of this study revealed the simultaneous coexistence of MC and CMC in strain CA28 when grown on a mixture of aniline and 3-CA. |
