title: Tryptophan in Kinixys crosa hemoglobins.
abstract: The hemoglobins, THI and THII, isolated from the red cells of the testudinid Kinixys crosa each have 3 tryptophan residues/18,000 daltons. Total number of amino acid residues for the proteins are therefore 156 and 155/18,000 daltons respectively.
