Multiple sequence alignment of the deduced amino acids encoded by envelope gp41 gene of HIV-1 from mother-infant pair E after perinatal transmission. Each line refers to a clone identified by a clone number preceded by ME (for mother E sequences) and IE (for infant E sequences). The sequences of pair E are aligned to consensus B (cons B) on top. Dots indicate amino acid agreement with cons B, dashes represent gaps, and asterisks represent stop codons. The functional motifs of gp41 are indicated above the alignment.
