Nucleotide substitutions within U5 are critical for efficient reverse transcription of human immunodeficiency virus type 1 with a primer binding site complementary to tRNA(His).

Abstract excerpt

Sequence analysis of integrated proviruses of human immunodeficiency virus type 1 (HIV-1) which utilize tRNA(His) to initiate reverse transcription [virus derived from pHXB2(His-AC-TGT)] revealed five additional nucleotide substitutions in the U5 and primer binding site (PBS) regions (ATGAC for CCTGT at nucleotides 152, 160, 174, 181, and 200, respectively) (Z. Zhang et al., Virology 226:306-317, 1996). We...
