#SPACEFILL CDR CONTACT ATOMS
#within 2., none; within 3., 5 atoms.
#L tyr50, H asp100 tyr101 gly53
#within 3.5, 21 atoms. all CDR (one not recog, L-Thr53)
#within 3.75, 31 atoms. all CDR
#within 4.0, 48 atoms. all CDR and one recognized FR2(L)
#within 4.1, 52 atoms (no new AA's)
#within 4.2, 58 atoms. (adds recog non-CDR L-tyr49, CDR H-arg99)
#now missing only L-his30.
#within 4.3, 63 atoms (no new AA's)
#within 4.4, 69 atoms (no new AA's)
#within 4.5, 71 atoms (no new AA's)
#within 4.6, 76 atoms (no new AA's)
#within 4.7, 80 atoms (no new AA's)
#within 4.9, 84 atoms (no new AA's)
#within 5.3, 104 atoms (1 new AA: nonrecognized CDR H-gly33)
#within 5.6, 116 atoms (1 new AA: nonrecognized CDR L-ile29)
#THEREFORE, we'll sacrifice L-his30 and stop at 4.2, 58 atoms.
