Tang J, Olson N, Jardine PJ, Grimes S, Anderson DL, Baker TS (2008) DNA poised for release in bacteriophage phi29. Structure 16:935–943The reviewers are correct: we do not see a decrease in donor fluorescence while observing acceptor fluorescence when determining FRET upon ClpB oligomerization in absence of ATP. A correlation between loss and gain of donor and acceptor fluorescence is observed in presence of ATP and in all cases for the repressed ClpB-E432A variant, which shows stronger motif 1–motif 2 interactions. We cannot provide a straightforward explanation for this difference, which is now stated in the Results section. Starting from where the head of the first vector ends, draw the second vector to scale in the indicated direction. Label the magnitude and direction of this vector on the diagram.

In this unit, the task of summing vectors will be extended to more complicated cases in which the vectors are directed in directions other than purely vertical and horizontal directions. For example, a vector directed up and to the right will be added to a vector directed up and to the left. The vector sum will be determined for the more complicated cases shown in the diagrams below. Represent each displacement vector graphically with an arrow, labeling the first \(\mathbf{A}\), the second \(\mathbf{B}\), and the third \(\mathbf{C}\), making the lengths proportional to the distance and the directions as specified relative to an east-west line. The head-to-tail method outlined above will give a way to determine the magnitude and direction of the resultant displacement, denoted \(\mathbf{\mathbf{R}}\).

The cephalocaudal trend is often contrasted with proximodistal development which refers to growth that occurs from the center of the body outward towards its periphery. This type of growth is seen in infants as they learn how to move arms before they can control fine finger movement. in vivo screens for inhibitors of any target protein of interest. In particular, the Split Intein Circular Ligation of Protein and Peptides (SICLOPPS) system exploits spontaneous protein splicing of inteins to produce intracellular cyclic peptides. A previous SICLOPPS screen against Aurora B kinase, which plays a critical role during chromosome segregation, identified several candidate inhibitors that we sought to recapitulate by chemical synthesis. We describe the syntheses of cyclic peptide hits and analogs via solution-phase macrocyclization of side chain-protected linear peptides obtained from standard solid-phase peptide synthesis. Cyclic peptide targets, including cyclo-[CTWAR], were designed to match both the variable portions and conserved cysteine residue of their genetically-encoded counterparts. Synthetic products were characterized by tandem high-resolution mass spectrometry to analyze a combination of exact mass, isotopic pattern, and collisional dissociation-induced fragmentation pattern. The latter analyses facilitated the distinction between targets and oligomeric side products, and served to confirm peptidic sequences in a manner that can be readily extended to analyses of complex biological samples. This alternative chemical synthesis approach for cyclic peptides allows cost-effective validation and facile chemical elaboration of hit candidates from SICLOPPS screens.
