Expert Solution & Answer

Answer to Problem 1P

The transgenic nematode would avoid the attractant and the normal nematode will be attracted to it.

Explanation of Solution

Given:

The neuron AWA express receptors, to which the normal nematodes are attracted. Another neuron AWB express receptors, which is avoided by nematodes. A transgenic nematode is made, in which the receptors for the attractant is produced by AWB, not AWA.

Explanation:

In the case of normal nematodes, the attractant molecules would excite the AWA, so they would be attracted. In the case of transgenic nematodes, the attractants would produce an opposite response, as the receptors for the attractants would be AWB. The message transcribed the AWB neuron would generate a message that this substance should be avoided. So, the behavior of the nematodes would be avoiding attractant.

The beta-lactamase hydrolyzes the lactam-ring in penicillin. Describe the mechanism of hydrolysis, insuring to include the involvement of S, D, & K in the reaction sequence. Please help

To map the active site of beta-lactamase, the enzyme was hydrolyzed with trypsin to yield a hexapeptide (P1) with the following amino acids. Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu. P1, P2, and P3 contain the active site serine. Why doesn't D in this hexapeptide not participate in the hydrolysis of the beta-lactam ring even though S, K, and D are involved in the catalyst?
