HIT1/YJR055W Additional Physico-chemical Properties Help

Physico-chemical properties were determined using the ProtParam tool available through ExPASy to analyze the primary protein sequence for atomic composition, extinction coefficient, estimated half-life, instability index and aliphatic index. Transcript translation calculations were determined using CodonW.
