The protein in this puzzle is from a human monocyte, a type of white blood cell.
The puzzle protein has 71 segments with the sequence:
The sequence is found in these Protein Data Bank entries:
The puzzle protein can have two disulfide bridges, identified in 4R8I as 11-36, and 12-52. The model in 4R8I omits the methionine which appears at segment 1 in the puzzle, so you must add one to the residue numbers in the PDB. Similarly, the model for 1DOL has the methionine as residue 0, so once again you must add one to get the Foldit segment number.
