Abstract
The amino acid sequence of the fetal chain of yak haemoglobin was determined.
The sequence is the same as that of the fetal chain of bovine haemoglobin. Phenylalanine is
present at position 12 of the helix A in the fetal chain while tryptophan is the amino acid at
this position in the β-chain of yak adult haemoglobin. This amino acid replacement may be
responsible for the higher oxygen affinity of yak fetal haemoglobin than yak adult haemoglobin.
