D1D2, IG-LIKE V-TYPE AND IG-LIKE C2-TYPE 1 DOMAINS

TLS refinement was performed with PHENIX. The anisotropic B-factor in ANISOU records is the total B-factor (B_tls + B_individual). The isotropic equivalent B-factor in ATOM records is the mean of the trace of the ANISOU matrix divided by 10000 and multiplied by 8*pi^2 and represents the isotropic equivalent of the total B-factor (B_tls + B_individual). To obtain the individual B-factors, one needs to compute the TLS component (B_tls) using the TLS records in the PDB file header and then subtract it from the total B-factors (on the ANISOU records).
YU2core/CD4 d1d2 from PDB entry 1RZK and 412d Fab from PDB entry 1RZG

Envelope glycoprotein gp160, T-cell surface glycoprotein CD4, anti-HIV-1 antibody 412d light chain, anti-HIV-1 antibody 412d heavy chain
Structure of tyrosine-sulfated 412d antibody complexed with HIV-1 YU2 gp120 and CD4

this entry contains the crystallographic asymmetric unit which consists of two gp120/cd4/412d complexes. chain A, B, C, and D form one complex, and chain E, F, G, and H form the other.

The largest off-origin peak in the Patterson function is 4.47% of the height of the origin peak. No significant pseudotranslation is detected.
