Denitrification by yeasts and occurrence of cytochrome P450nor in Trichosporon cutaneum.

abstract：:In this study, internal size variations in the VanA gene cluster Tn1546, encoding resistance to glycopeptides, is described. Studies of previously uncharacterized size variations of an internal region, encoding the vanX and vanY genes of Tn1546, revealed that these variations were due to the presence of the IS sequenc...
