What is arcs: Definition and 31 Discussions

Archaeosine synthase (EC 2.6.1.97, ArcS, TgtA2, MJ1022 (gene), glutamine:preQ0-tRNA amidinotransferase) is an enzyme with systematic name L-glutamine:7-cyano-7-carbaguanine aminotransferase. This enzyme catalyses the following chemical reaction

L-glutamine + 7-cyano-7-carbaguanine15 in tRNA + H2O



⇌


{\displaystyle \rightleftharpoons }
L-glutamate + archaeine15 in tRNAIn Euryarchaeota the reaction is catalysed by ArcS.

    Geometry problem with arcs in a triangle

    In the figure, the point S is located inside the section FE. Starting from S, as indicated in the figure, six circular arcs are drawn step by step around arcs around A, C, B, A, C, B are drawn. Show that the sixth arc leads back to S and that the six arcs together are then exactly as long as the...

    Electric field created by two charged circular arcs?

    The strategy will be to figure out what ##dq##, ##\hat{r}_{dq,p}##, and ##r_{dq,p}## are, plug them into the expression for ##d\vec{E}_{p_r}##, then integrate over ##d\vec{E}_{p_r}## to obtain ##\vec{E}_{p_r}##, the electric field at ##P## due to the arc on the right. Then I will repeat the...

    Resultant field at the center of two semicircular current arcs

    So the magnetic field induced at the center of a current-carrying loop is given by: B = μ0 i /2r where r is the radius of the loop In the case of a semi-circular loop, this becomes B = μ0 i /4r In the question, i = 2A, r1 = 1m and r2 = 2m So, field induced at the center of first semicircular...

    Why Do Arcs Form Between Fork Tines in a Microwave Oven?

    Some fireworks in our microwave from peeling paint got me thinking... If you place a fork inside, arcs will form between the tines. Why? Presumably the EM field is inducing different potentials on each tine, and the pointiness concentrates the field enough to exceed the breakdown voltage there...

    How do arc furnaces sustain themselves without significant resistance?

    I'm highly interested in building my own small arc furnace for hobby use. Thus, I want to understand the nature of electrical arcs before proceeding to have maximum control over my design. So far, I know that electrical arcs form when the dielectric strength of the material (in this case, a gas)...

    Experimenting with Capacitor Discharge Arcs: What's Going On?

    Hi there.. I was experimenting with capacitor discharge arcs. I charged a 340μF cap to 9v and shorted the terminals of the cap. Zap! Sparks!.. Then the terminals got stuck to each other as if they had been glued together! It took me 3-4 seconds pulling at them to separate them. It happens every...

    Is there a relation between log and arcs for complex numbers?

    If there is a formula relating the exponential with sine and cosine normal and hyperbolic (exp(ix) = cos(x) + i sin(x), exp(x) = cosh(x) + sinh(x)), there is also a formula relating the logarithm with arcsin, arccos, and arcsinh arccosh?
