Figure 4.

Multiple sequence alignment of deduced amino acids of NC and p6 from mother-infant pairs F and H, including both infant H twins (I1H and I2H). Within the alignment, the top sequence is the NC consensus B (ConBNC) sequence to which the mother-infant pair sequences are compared. Each line of the alignment represents one clone sequence, and is identified by a clone number with M referring to mother and I referring to infants. The dots represent agreement with the consensus sequence, while substitutions are represented by a single letter amino acid code. Stop codons are shown as asterisks (*). The functional domains within the sequence are indicated above the alignment.
