We present an evaluation of the results of our ZDOCK and RDOCK algorithms in Rounds 3, 4, and 5 of the protein docking challenge CAPRI. ZDOCK is a Fast Fourier Transform (FFT)-based, initial-stage rigid-body docking algorithm, and RDOCK is an energy minimization algorithm for refining and reranking ZDOCK results. Of the 9 targets for which we submitted predictions, we attained at least acceptab...
fabms analysis of t-lb peptide before and after one cycle of edman degradation indicated an unblocked n-terminal thr residue for this tryptic peptide. in contrast , our data showed a molecular protonated ion, mh + for t- la peptide at 655 mass units (mu) which is 42 mu higher than the mh ion of t- 1b peptide. in addition, t- la peptide was not amenable to one cycle of manual edman degradation. ...
The new, belonging to the streptothricin-group antibiotics AN-201 I, II and III were found to be produced by a soil actinomycete identified as Streptomyces nojiriensis C-13. The chemical structures and the physical and spectroscopic properties of these compounds are reported here. On the basis of NMR and fast atom bombardment mass spectrometry (FAB-MS) spectra the antibiotics were identified as...
Glycosphingolipids occur in most hi her organisms as 200 compounds in this class have been isolated and chemically characterized. In this aper, we compare the structures of several complex glycosphingoEpids and discuss the utilit of fast atom bombardment mass spectrometry in the MSldS mode with collision-assisted dissociation of the ceramide ion to study details of the ceramide structure. The f...
Fast atom bombardment (FAB) mass and MS/MS spectra of a novel quinone antibiotic are presented. Their interpretation is based upon the examination of reductive behavior of model quinones in FAB solvents.
