our findings suggest that ( i ) the methicillin resistance locus is identical to the structural gene for pbp 2a , ( ii ) although the ability to produce pbp 2a is essential for resistance , the mics for the majority of cells are not related to the cellular concentration of pbp 2a , and ( iii ) high mics and homogeneous expression of resistance require the products of other distinct genetic elements as well .
