Neurobiology course. Please explain the answer.
Tyrosine hydroxylase is a substrate for which of the following protein kinases?
a, PKA
b. PKC
c. CaM kinase II
d. MAP kinase
e. all of the above
Tyrosine hydrodroxylase is a substrate for all of the protein kinase including Protein kinase A (PKA) , Protein Kinase C( PKC) and CaM kinase 2 and MAP kinase. This enzyme will hydroxylase tyrosine and it's product helps in regulating the activity of the kinase listed above. That's why right option is all of the above (D) .

15. Which statement below about the interconversion of the alpha and beta anomers of D-glucopyranose is true? The interconversion requires an enzyme called an isomerase The interconversion is spontaneous in water because the acetal functionality is labile The interconversion is spontaneous in water but is slow which is why we typically draw glucose having one anomeric form...

You
perform an assay on the activity of the JAK tyrosine kinase using a
40 microliter aliquot of a lysate prepared from cells labeled for
six minutes with radioactive cysteine. the total volume of the
lysate is 5 milliliters (ml). In the aliquot, you measure the
amount of all proteins and determine the presence of 13 micrograms
of protein in 75 microliters of lysate. which of the following is
the best calculation of the specific activity of the kinase in...
