The P200 protein of Mycoplasma pneumoniae shows common features with the cytadherence-associated proteins HMW1 and HMW3

Gene. 1996 May 24;171(1):79-82. doi: 10.1016/0378-1119(96)00014-5.


The gene coding for the P200 protein of the bacterium, Mycoplasma pneumoniae (Mp), was cloned and sequenced. The sequence-derived data and biochemical data indicated that P200 has several features in common with the well characterized cytadherence-associated proteins, HMW1 and HMW3. These features consist of abnormal migration in SDS-PAGE, a central acidic domain with a high Pro content, repeated peptide blocks within the Pro-rich domain and P200 partitioning similar to HMW1 and HMW3 in the insoluble fraction after extraction of Mp with the detergent Triton X-100.
