Abstract

A collection of variant plasmids that express the human immunodeficiency virus (HIV) reverse transcriptase as trpE fusion proteins were generated and scored for their ability to produce stable, active proteins. Trimming portions of the viral pol gene resulted in dramatic increases in yield over earlier constructs; the accumulation of high levels of enzymatically active protein in this system was increased by the retention of the trpE sequences at the amino terminus. A new in situ gel activity assay was used to demonstrate that the major induced protein, containing approximately 68 kD of viral sequences, was the active species.
