Three extra peaks in 15N HSQC and more than 25 extra peaks in 13C HSQC were identified. These peaks are grouped into three fragments, one assigned as GlcNAc, the other two fragments could not be accurately assigned given the limited information we have, but they are likely to belong to glycans. These fragments display intra NOEs only and remain solvent exposed with strong and narrow line widths. NMR relaxation data showed that these unknown modifications are highly mobile and no interaction with viv0002. Heterologously expressed viv0002 was confirmed by LC-MS. A mass shift of 178 Da of 15N-labeled viv0002 was detected whereas a shift of 72 Da for 13C/15N-labeled sample. However, neither of results matches any three unknown fragments seen in the NMR spectrum with MW 202 Da, 155 Da and 204 Da, respectively. The nature and functional consequence of the unknown fragments/modifications to viv0002 are not understood at this stage. The structure deposited provides the basis of the future investigation.
