Authentic Biochemistry

Correction: In my lecture I incorrectly used the W single letter designation as representing tyrosine. I miss-spoke. W=tryptophan while Y=tyrosine. The WW domain discussion is important for specific protein:protein interactions wherein the tryptophan (W) residues (found in the beta1 and beta 3 folds) are separated by 20 -22 amino acids that contain certain tyrosine (Y) residues in the beta2 region which may become phosphorylated thus generating phosophotyrosine binding (PTB)domains that are recognized by other proteins. I apologize for the error. References Exp Biol Med (Maywood). 2015 Mar; 240(3):375–382 Cellular Physiology and Biochemistry (2017) 41 (3): 1189–1198.
