The real coordinates are found by studying a couple of
proteins:
P11766; the sum of the positions of the zinc-binding cysteines are
AAA
P49913; the sum of the positions of the residues involved in
disulfide bond formation are BBB
P45379; there are two crystal structures published in 2003. The
resolution of the most accurate one is CCC
P0CG48; The square of the number of recognised ubiquitin-like
domains is DD
Then calculate:
XXX = AAA + 21
YYY = BBB + CCC - DD + 22
The coordinates are:
N 58° 23.XXX
E 015° 34.YYY
