Illinois, Urbana, Ill. 61801 The most common ("Bottom-Up") way to identify proteins is to break them into fragments with enzymes in solution, and then analyze the pieces by liquid chromatography/mass spectrometry. However, if the proteins can be ionized intact in the gas phase, and then fragmented ("Top-Down" proteomics), identification is more direct and certain, and the location(s) of chemical modifications (e.g., phosphates, sugars, etc.) become unequivocal. Recently, it has become possible to fractionate a protein mixture by gel electrophoresis, and then sort the contents by nanocapillary liquid chromatography and ultrahigh-resolution mass spectrometry and MS/MS. A single injection yields ~40 detectable proteins, about half which yield ProSight (automated) identifications. For example, the Figure shows differences in phosphorylation for proteins identified in asynchronous and M phase arrested HeLa cells. Asynchronous (A) and M-phase arrested (B) HeLa proteins are confidently identified, with the phosphorylations designated in red. A fragment map (C) is shown for the doubly phosphorylated 60S acidic ribosomal protein. At higher magnetic field (21 T), such identifications should extend to the larger proteins found in humans. *Suuported by NSF Division of Materials Research through DMR-06-54118, and the State of Florida.

La Jolla Laboratories, 10777, Science Center Drive, San Diego, CA  92121 The most detailed probes of drug receptor architecture are nuclear magnetic resonance and x-ray crystallography. However, it is often necessary to "snip" away all but the putative critical core "domain", to make it amenable to NMR or x-ray analysis. One then needs to validate that approach, by somehow comparing the domain and intact enzyme, to see if the domain does in fact retain the same critical structure (e.g., catalytic site and regulatory site) as the intact protein. We recently used hydrogen/deuterium exchange for such a validation for tyrosine kinase (KIT), the target for drugs (imatinib and sunitinib) to treat abdominal cancer. The Figure shows that deuterium uptake (a measure of exposure to solvent) is essentially the same for the critical segments of the enzyme, with or without the 60 amino acid segment known as the "kinetic insertion domain" (KID), thereby confirming (in this case) that the domain does accurately represent the receptor structure. *Suuported by NSF Division of Materials Research through DMR-06-54118, NIH 78359, and the State of Florida.

Airport Blvd, Sugar Land, Texas 77478 Calcium and sodium naphthenates are solid deposits and emulsions formed by the interaction of naphthenic acids in crude oil with divalent (Ca2+, Mg2+) or monovalent (Na+, K+) ions in produced waters. We have determined detailed chemical compositions of calcium and sodium naphthenates from the field based on high resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). In all cases, calcium naphthenate deposits consist predominately of tetraprotic acids with a C80 hydrocarbon skeleton whereas sodium naphthenate emulsions consist mainly of specific monoprotic saturated carboxylic acids. The Figure is an abundance-weighted plot of double bond equivalents (rings plus double bonds to carbon) versus number of carbons in those sodium naphthenate deposit molecules that contain carbons, hydrogens, and two oxygen atoms. Thus, sodium naphthenates are simply saturated (i.e., (-CH2-)n carbon chains terminated in a -CO2H group containing a single C=O double bond. Understanding the specific chemical nature of such deposits is the first step toward preventing their formation. *Suuported by NSF Division of Materials Research through DMR-06-54118, and the State of Florida.
