Protein phosphorylation

... 2. 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 ...

bacterial isoleucine synthesis pathway

... and i stumbled upon feedback inhibition as a gene expression mechanism in prokaryotes. as an example, they had the isoleucine synthesis from threonine, when isoleucine inhibits the treonindezaminase enzyme. All good, except i noticed something there that seemed very very strange. on of the ...
