# Results   ## Protein production and baseline values   In total, 123 proteins, including native BglB, were purified with immobilized metal affinity chromatography and eluted in 200 μL HEPES buffer. Of the 123 proteins synthesized, 85 proteins express and purify as soluble protein. Greater than 65% of mutants maintained the yields obtained by native BglB while roughly 30% did not express and purify as a soluble protein above our limit of detection (0.1 mg/mL) for protein yield after purification based on A280 and SDS-PAGE. Of the 85 proteins with expression, 76 mutants displayed apredictive  melting temperature that  fit to our logistic equation. Native BglB displayed an average melting temperature of 39.6 C.
