Example sentences for: phenylalanine
How can you use “phenylalanine” in a sentence? Here are some example sentences to help you improve your vocabulary:
Tetraethylammonium is known as a pore-occluding blocker of voltage-gated potassium channels [ 1 ] , but it also blocks other cationic channels such as calcium-dependent K +channels [ 2 3 ] and the nicotinic acetylcholine receptor [ 4 ] . TEA at 0.1 to 10 mM also inhibits osmotic water flux through human AQP1 channels expressed in Xenopus oocytes, decreasing the net swelling rate in hypotonic saline by 30-40% as compared to AQP1-expressing oocytes not treated with TEA [ 5 ] . This blocking effect on osmotic water flux was demonstrated to involve AQP1 channels specifically by using site-directed mutagenesis (tyrosine 186 to phenylalanine) to generate a Y186F AQP1 channel that is insensitive to block by TEA, but retains sensitivity to block by mercury.
The F158A mutant exhibited higher K m values when using the cephalosporins as substrates, suggesting an interaction of the cephalosporins' substituents with the phenylalanine on the loop that extends over the active site.
The implied transcriptional control of DAHP synthase by L-tryptophan potentially could produce growth inhibition by L-tryptophan because of limitation of precursors needed for L-phenylalanine and L-tyrosine biosynthesis.
These chlamydial proteins might be broad-specificity transporters of tryptophan, tyrosine, phenylalanine and perhaps kynurenine as well.
AroR is much larger and exhibits complex allostery, being activated by L-tryptophan and inhibited by L-tyrosine in the case of yeast [ 9] or being activated by L-tryptophan and inhibited by both L-tyrosine and L-phenylalanine in the case of higher plants [ 10].
