However, prior to the initiating methionine of the monomer B, there is an additional density of an unrecognizable shape with the molecular mass of 100-150 Dalton. Our mass spectrum also reveals a peak, corresponding to 130 Dalton. Moreover, the unknown chemical entity possibly is covalently bound to the methionine.
