FIG. 7.
Multiple sequence alignment of amino acids 129 to 147 in IRP1s of various species currently deposited in Swiss-Prot. Ser-138 (asterisk) is conserved only in the IRP1 proteins from vertebrates. The genInfo identifier (gi) numbers of all molecules are indicated on the right. The alignment was made by the Clustal W algorithm (MacVector software, version 6.5.3).
