Separation of human small‐intestinal sucrase from isomaltase

Does sucrase—isomaltase always exist as a complex in human intestine?

“…In addition studies on human small intestine suggested the presence of free sucrase [4-61 and isomaltase [ 5,6]. However, papain treatment or autolysis used in these studies to release the enzymes may have induced changes in the peptide chains resulting in dissociation of the sucraseisomaltase complex.…”
