Phenylalanine in diet soda: Is it harmful? - Mayo Clinic
May 24, 2023Genetic conditions are passed through families. In people with PKU, phenylalanine can cause intellectual disability, brain damage, seizures, and skin and other problems. Intellectual disability is slow learning and skill building. Phenylalanine is in many protein-rich foods, such as milk, eggs and meat. Phenylalanine also is sold as a dietary ...

PAH gene mutation Analysis of the DNA of the Phenylalanine hydroxylase (PAH) gene in a patient with phenylketonuria revealed a mutation in the protein coding region whose predicted effect would be to replace the amino...
In terms of the way that the question is worded, I imagine the most likely answer would be that the amino acid substitution D > H disrupts the folding of the protein so that it is recognised as being aberrant and is rapidly degraded.

Is glutamate always involved in the deamination and amination of the other amino acids? For example, are there pathways for the deamination of phenylalanine that simply produce ammonia or pathways for it to be synthes...
For most amino acids, the removal of the α-amino group involves α-ketoglutarate and glutamate. The amino group is first transferred to a-ketoglutarate by transaminases, and the resulting glutamate is then deaminated (via glutamate dehydrogenase) to yield ammonia.  is an enzyme that catalyzes the chemical reaction
ATP + L-phenylalanine diphosphate + N-adenylyl-L-phenylalanine Thus, the two substrates of this enzyme are ATP and L-phenylalanine, whereas its two products are diphosphate and N-adenylyl-L-phenylalanine.

Redundancy of the genetic code One particular codon codes only for one amino acid, but an amino acid can be coded for by several different codons. Now according to the genetic code, the codon `UUU` codes for the amino...
The tRNA for Phenylalanine has an anticodon - `GAA` which can pair with both `UUU` and `UUC` but not `UUA`.

Mutation That Loses Stop Codon Someone asked this in my class and my instructor wasn't sure in her answer, doesn't anyone know what happens in protein synthesis if a mutation causes mRNA to not possess a stop codon? W...
No, this will not happen. mRNAs are inspected in the nucleus before they are exported into the cytoplasm (at least in eukaryotes), where transcription and translation don't happen at the same place. This ensures that no mRNAs without stop codons or premature stop codons are exported. This phenomenon...

Efficient biosynthesis of resveratrol via combining phenylalanine and ...
Mar 8, 2023Background: Resveratrol is a commercially available stilbenoid widely used as dietary supplements, functional food ingredients, and cosmetic ingredients due to its diverse physiological activities. The production of resveratrol in microorganisms provides an ideal source that reduces the cost of resveratrol, but the titer in Saccharomyces cerevisiae was still much lower than that in other hosts.
