What is Effect of the polycyclic aromatic hydrocarbon, benzopyrene, on the intracellular protein composition of Fusarium solani and Fusarium oxysporum about?

In the present study, we compared the two-dimensional polypeptide maps of proteins extracts from Fusarium solani and Fusarium oxysporum, two telluric fungi previously isolated from contaminated soil and shown to have good and poor benzo1⁄2apyrene degrading abilities, respectively. Their protein compositions were analyzed when grown in the presence and absence of benzo1⁄2apyrene. We provide evidence that benzo1⁄2apyrene induced specific protein synthesis in F. solani. The induced polypeptides were mainly observed in the acidic part of gels at 50; 45 and 30 kDa. In contrast, no additional polypeptides were detected in F. oxysporum when grown in the presence of benzo1⁄2apyrene. The polypeptides sequence of 45 and 30 kDa polypeptides have high similarity (44% and 67%, respectively) with a porphobilinogen deaminase (EC 2.5.1.61), a key enzyme in the heme and cytochrome P450 biosynthesis pathway.
