(A) Immunoblot of variants leading to SHV-129 showing the various expression levels of these proteins in whole cell bacterial preparations. (B) Immunoblot of variants leading to SHV-129 showing the various expression levels of these proteins in soluble fraction preparations. SHV-2 is G238S, SHV-5 is G238S-E240K, and SHV-129 is G238S-E240K-R275L-N276D.
