Hemoglobin Brockton [beta 138 (H16) Ala—-Professional] has minimal oxygen affinity but electrophoretic mobility and hemolysate binding are ordinary, suggesting which the substitution at beta 138 does not disrupt important polar interactions, like the hydrogen bonds and salt bridges involving Asp 137 and Professional 138, that lead on the cooperative oxygen-binding https://nicolaslecourtmansion.com
