The AEROSPACI score for this entry is lower than the SPACI score because human-curated comments on the entry in SCOPe contain the phrase chimer. The full comment is: "chimeric affinity matured antibody; part of metal chelatase catalytic Fab 7G12; chimeric affinity matured antibody; part of metal chelatase catalytic Fab 7G12; chimeric affinity matured antibody !SQ P01750 20-116 #! HV06_MOUSE Ig heavy chain V region 102 precursor; part of metal chelatase catalytic Fab 7G12; chimeric affinity matured antibody !SQ P01642 21-115 #! KV5I_MOUSE Ig kappa chain V-V region L7 precursor"
