[ccp4bb] Density at a short distance near Tyrosine

Hi all, I have determined the structure of a protein at 3Å resolution. The protein has 6 chains in the asymmetric unit. In all these 6 chains I see a density near tyrosine which is at a distance of 2.1 from the OH group of tyrosine. Since this distance is short for a hydrogen bond we are skeptical
