Bioluminescence in Vibrio fischeri is dependent on
A.) phosphorylation of CheY protein
B.) autoregulation of the luxI gene
C.) destabilization of luxM mRNA
D.) posttranslational regulation of Spo0A protein
Homework Answers
Answer:
B.) autoregulation of the luxI gene
Explanation:
There are two genesessential for cell density regulation of Vibrio fischeri bioluminescence:
1. luxI, which codes for an autoinducer synthase; and luxR, whichcodes for an autoinducer-dependent activator of the lumines-cence gene
Add Answer to:

A.) phosphorylation of CheY protein
B.) autoregulation of the...

Phosphorylation-dependent binding of F-box protein B-TrCP containing E3 ubiquitin ligase to human WEE1A. S123 is phosphorylated by a CDK and the phosphorylation primes CK2 to phosphorylate S121 resulting in creation of a B-TCP phosphodegron (EEGFGpS121) that is responsible for the instability of WEE1A during interphase. At the onset of M-phase, when activated Plk1 accumulates, Plk1 binds to WEE1A to the PBD binding motif surrounding PS123 (SpSP) via its PBD and phosphorylates S53 resulting in generation of the second phosphodegron (DpSAFQE)....

1. Vibrio bacteria are abundant in ocean and aquatic environments. Suppose you wish to isolate Vibrio- specific bacteriophages from seawater. You enrich your sample by spiking the seawater with growth medium and Vibrio fischer. You then isolate your phage and plate it on lawns of bacterial growth to enumerate how many PFUs/mL are in your sample. a. You set up a series of 10-fold phage dilutions out to a TDF of 10', and you plate each of those dilutions mixed...

Rhodopsin, a light-sensitive GPCR whose role in vision is dependent on its phosphorylation status, is influenced in part by the protein arrestin. Which of the following is true in regards to rhodopsin and vision? Select one: a. Rhodopsin phosphatase increases the degree of rhodopsin phosphorylation b. Arrestin binds to the completely phosphorylated opsin to inhibit signaling c. Rhodopsin activation promotes the opening of a cGMP-gated ion channel d. none of the above

The SR protein SRn2
can auto-regulate its own level using a type of alternative
splicing known as "unproductive splicing." The SRn2 gene
(shown above) can be alternatively spliced to give two distinct
mRNAs: mRNA (A) is stable and actively translated, while mRNA (B)
includes the alternative exon 2a and is targeted by nonsense
mediated decay (NMD). It is observed that when levels of SRn2
protein rise, the levels of its productively spliced mRNA
fall (and vice versa).
