Table 4 Capsid protein similarity. The similarity of the capsid protein domains are tabulated as: (a) RMSd (unweighted) and (b) PSId, both as calculated by the SAP program. Upper-right triangle: over the common core of the C-terminal domain and Lower-left triangle: over the common core of the N-terminal domain. The proteins are identified as: D1D = RSV [1d1dA], QRJ = HTLV-I [1qrjA], E6J = HIV-I [1e6jP], EIA = EIAV [1eia ].
