Design Notes

Added a Cysteine for immobilization (D256C) opposite to the active site region. Removed C135A and C189S to ensure only one cysteine would bind to an immobilization linker arm. Amino acid substitution considerations were made using an intensive BLAST search to ensure conservation. A T22A modification was made based on previous evidence of this substitution permitting phosphate binding in the physiological range.
