Bacterial expression of an active tyrosine kinase from a protein A/truncated c-src fusion protein.

abstract：:We present here a new set of aminoglycoside-arginine conjugates (AACs) that are either site-specific or per-arginine conjugates of paromomycin, neamine, and neomycin B as well as their structure-activity relationships. Their binding constants (KD) for TAR and RRE RNAs, measured by fluorescence anisotropy, revealed dep...
