Tyrosine

... Is it simply mimicing because the presence of the -COOH group in Asp/Glu is similar to a phosphate group? 3. Can Asp/Glu mimic threonine (Thr) or tyrosine (Tyr) phosphorylations as well? I guess it could for Thr as well, since Ser and Thr are very similar in shape. Thanks in advance!

I was given the following question: The cdc25 gene of the fission yeast Saccharomyces pombe encodes a phosphatase which dephosphorylates the tyrosine 15 residue of the cyclin-dependent kinase (Cdk). Dephosphorylation of tyrosine-15 of Cdk activates its kinase activity. You introduced a 2nd copy ...

... take place in the pheriphery - just like you suspected. edit: RTEs can be distinguished from normal naive CD4+ cells primarily by their protein tyrosine kinase 7 expression, and they are less responsive and have poor effector function. So, does knowing this have any practical significance? The ...

... for this strand. So I found the mRNA: - AUGACAACGCUUACGUUAA- Then found the tRNA: - UAC UGU UGC GAA UGC AAUU?- Therefore the amino acids are: Tyrosine, Cysteine, Cysteine, Glutamic acid, Cysteine, Asparagine? or Isoleucine? I am confused because there is no Start or End. Is there not supposed ...
