Sometimes scientists have too much time on their hands! In a 2013 study it was reported that Proline accounts for 6.3% of the 10,882,808 protein amino acids with 46 proteins identified as having no proline. One protein however, long keratinocyte envelope protein (SPRR2G) composed of 73 amino acids contains 39.7% proline. If -10 mg of this protein was dissolved into 50 mM proline buffer how many proline (FW 115.1 g/mol) molecules would exist in one mL of the solution. Assume for unknown protein that each amino acid is -110 Da.
