transaminase
Let an agent explain transaminases, relay mechanism, metabolic roles, clinical testing and biocatalysis from biochemistry and clinical sources, describe the named enzymes, explain that abnormal liver enzyme results need interpretation by a clinician, and distinguish transaminases from deaminases, other transferases and liver function as a whole.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain transaminases, relay mechanism, metabolic roles, clinical testing and biocatalysis from biochemistry and clinical sources, describe the named enzymes, explain that abnormal liver enzyme results need interpretation by a clinician, and distinguish transaminases from deaminases, other transferases and liver function as a whole.
An enzyme, also called an aminotransferase, that catalyses the transfer of an amino group from an amino acid to a keto acid using the cofactor pyridoxal phosphate, central to amino acid synthesis and breakdown, with many specific enzymes such as D-amino acid aminotransferase, branched-chain aminotransferase, lysine-pyruvate 6-transaminase, methionine-glyoxylate transaminase and 3-amino-2-methylpropionate transaminases; alanine aminotransferase ALT and aspartate aminotransferase AST are measured in blood as liver function tests, and engineered transaminases are used to make chiral amines for drugs.
What it is for: Transferring amino groups in metabolism.
It can be explain mechanism; relay metabolic and clinical roles; describe named enzymes; route abnormal results to clinicians.
Distinguishing features

Industrial biocatalysts
What it looks like
Not a visible object; proteins.
Physical character
cofactor: pyridoxal 5-phosphate note - vitamin B6 derivative
EC subclass: 2.6.1 code
clinical markers: ALT and AST list
How it is recognised
Aminotransferase enzyme
D-amino acid aminotransferase, branched-chain aminotransferase, lysine-pyruvate 6-transaminase, methionine-glyoxylate transaminase, 3-amino-2-methylpropionate transaminases
Deaminases remove amino groups; other transferases move other groups; liver function tests include more than ALT and AST
