Pyruvate kinase type M2 is phosphorylated at tyrosine residues in cells transformed by Rous sarcoma virus

Abstract
Chicken embryo cells (CECs) contain pyruvate kinase (PK) type M2 (M2‐PK). Transformation of CECs by Rous sarcoma virus (RSV) leads to a reduction in the affinity of PK for the substrate phosphoenolpy...
