WebBiotinylation is an attractive approach for protein complex puriﬁ-cation due to the very high afﬁnity of avidin streptavidin for biotinylated templates. Here, we describe an approach for the single-step puriﬁcation of transcription factor complex(es) based on speciﬁc in vivo biotinylation. We expressed the bacterial BirA WebDec 2, 2024 · Although this protocol is useful for identifying protein-protein proximity interactions, it has several key limitations. First, this protocol is limited by the level of biotin ligase expression as we have found that overexpression of biotin ligase enzymes in the intestine leads to higher biotinylation activity than a single copy insertion.
