With the aid of monoclonal antibodies to the reverse transcriptase (RT) of human immunodeficiency virus type 1 (HIV-1), low-molecular-mass subunits (p29, p32, and p40) were identified in HIV-1 RT purified from HIV (HTLV-IIIB) virions by isoelectric focusing. Epitope mapping with synthetic polypeptides from various regions of the pol gene suggests that the low-molecular-mass subunits result from N-terminal cleavage of the p51 subunit. The subunits could be separated only by SDS-polyacrylamide gel electrophoresis and detected by immunoblotting. They could not be separated on chromatographic columns, suggesting that the subunits are complexed or conformationally arranged in such a way that their separation on the basis of molecular mass is not possible. The molecular mass of the active enzyme eluted from a chromatographic column (Sephacryl S-300) loaded with a mixture of the subunits was estimated to be 100 kDa.
