Okay. Am I right in assuming that since the sequence has a hydroxl modification, and hydroxlproline is not found in bacteria (at least so far), it means the protein is most likely animal in origin? If so, that means we don't need to sequence any Hell Creek bacteria to find potential contaminants, and we can pretty safely rule that the sequence is endogenous beyond reasonable doubt.
