Describe the specificity of aminotransferases for their substrates.
Homework Answers
Answer:-
Aminotransferases or transaminases are a group of enzymes that catalyze the interconversion of amino acids and oxoacids by transfer of amino groups. Aspartate aminotransferase (AST), formerly termed glutamate oxaloacetate transaminase (GOT), and alanine aminotransferase (ALT), formerly termed glutamate pyruvate transaminase (GPT), are the two aminotransferases of greatest clinical significance.
The specificity of individual enzymes determines the specific amino acid that serves as the other amino group donor. In the AST reaction, the l-amino acid is aspartate; for ALT, it is alanine.

Most enzymes are quite specific, catalyzing a particular reaction on a set of substrates that are structurally quite similar to one another. Discuss why this is advantageous from a biological perspective. Suggest why this is likely to be true from a chemical perspective. That is, why would it be difficult to evolve an enzyme with high catalytic activity but low specificity?

Join borosilicate glass substrates containing a-SiC:H films with substrates containing titanium films. This will be done by activating the surface of the wafers with APTMS ((3-Aminopropyl) trimethoxysilane) to subsequently bind these molecules with glutaraldehyde. ¿How can I improve biofunctionalization between APTMS ((3- Aminopropyl) trimethoxysilane) and glutaraldehyde?
