Remark 999 | SEQUENCE All chains in the entry are part of an engineered, chimeric protein construct. In the ...SEQUENCE All chains in the entry are part of an engineered, chimeric protein construct. In the construct, the amino-to-carboxyl order of the chains is: C-B-L-A. Chain C is a GSMG sequence that comes from the expression vector, B is the BRCA2 BRC repeat, L is the TGSTGSTGSTGSMG sequence linking chains B and A, and chain A is the RAD51 ATpase domain. Chain C appears as a separate entity because the two initial residues of chain B, 1517-8, are not visible in the density map. Likewise, the linker is not visible in the density map, with the exception of the first three residues:TGS. |
