We present a calculation of the renormalization coefficients of the quark bilinear operators and the K-K‾ mixing parameter BK. The coefficients relating the bare lattice operators to those in the RI/MOM scheme are computed nonperturbatively and then matched perturbatively to the MS‾ scheme. The coefficients are calculated on the RBC/UKQCD 2+1 flavor dynamical lattice configurations. Specifically we use a 163×32 lattice volume, the Iwasaki gauge action at β = 2.13 and domain wall fermions with Ls = 16
