Table 3.

Amino acid compositions and molecular masses of Bc-CPs. Observed values are obtained with ninhydrin-based analysis and MALDI-ToF mass spectrometry, whereas predicted values are derived from translated cDNA sequences. For the observed values, the maximum standard deviation is ~5% of the values shown.
