Identification of bioactive peptides in hypoallergenic infant milk formulas by CE-TOF-MS assisted by semiempirical model of electromigration behavior. Electrophoresis 2014; 34:1886-94.

Abstract
Biologically active peptides derived from complex bovine milk protein hydrolysates are of particular interest in food science and nutrition because they have been shown to play different physiological roles, providing benefits in human health. In this study, we used CE-TOF-MS for separation and identification of bioactive peptides in three hypoallergenic infant milk formulas. An appropriate sample cleanup using a citrate buffer with DTT and urea followed by SPE with Sep-Pack® C18 and StrataX™ cartridges allowed the detection of a large number of low molecular mass bioactive peptides. This preliminary identification was solely based on the measured experimental monoisotopic molecular mass values (M(exp)). Later, we evaluated the classical semiempirical relationships between electrophoretic mobility and charge-to-mass ratio (m(e) vs. q/M(α), α = 1/2 for the classical polymer model) to describe their migration behavior. The assistance of migration prediction proved to be useful to improve reliability of the identification, avoiding misinterpretations and solving some identity conflicts. After revision, the identity of 24, 30, and 38 bioactive peptides was confirmed in each of the three infant milk formulas. A significant number of these peptides were reported as inhibitors of angiotensin-converting enzyme, however, the presence of sequences with other biological activities such as antihypertensive, antithrombotic, hypocholesterolemic, immunomodulation, cytotoxicity, antioxidant, antimicrobial, antigenic, or opioid was also confirmed.

Abstract
In this chapter, the potential of capillary electrophoresis-mass spectrometry (CE-MS) for peptide analysis is demonstrated by the presentation of two different strategies typically followed in analysis of these biomolecules by CE-MS. The first one is a target-based approach and it is used to detect a toxic oligopeptide in a complex matrix. Namely, CE-MS using an ion trap MS analyzer is applied to detect and quantify γ-glutamyl-S-ethenyl-cysteine (GEC) bioactive dipeptide in a legume plant. The second one is a shotgun-like methodology used for proteomic analysis. Particularly, CE-MS using a time-of-flight MS analyzer is employed to investigate the substantial equivalence between a genetically modified (GM) variety of soybean and its conventional isogenic counterpart. These generic methods have broad applications for the analysis of peptides in a large variety of matrices, including applications in the area of proteomics and peptidomics.

Abstract
Cu, Zn-superoxide dismutase (SOD-1) is a homodimeric metalloenzyme that has been related to ALS (amyotrophic lateral sclerosis). The majority of ALS cases are sporadic while approximately 10% are inherited (familial ALS, FALS). Mutations in the amino acid sequence of human SOD-1 cause only 25% of the FALS cases, while the explanation for the rest is not clear yet. In this way, several authors have suggested the importance of posttranslational modifications or dimer dissociation on formation of the characteristic fatal intraneuronal SOD-1 aggregates. In this paper, we used capillary electrophoresis-electrospray mass spectrometry with an accurate mass and high-resolution time-of-flight mass spectrometer (CE-TOF-MS) for separation and characterization of standard bovine SOD-1 and human SOD-1 purified from erythrocytes. Two background electrolytes (BGEs) were used for CE-TOF-MS experiments in positive ion mode. An acidic BGE allowed detection of apo-monomer SOD-1, because the metal ions were completely released during the electrophoretic separation. The better sensitivity at acidic pH was especially interesting to detect different isoforms of human SOD-1. In contrast, a neutral BGE provided enhanced conditions for detection of the fully metalated dimeric and monomeric enzyme, but selecting an appropriate fragmentor voltage value in the TOF analyzer was critical to obtain reliable quantitative information. Anyway, only the metalated forms involving the main isoform of human SOD-1 were detected due to the lower sensitivity. Hence, the combination of both methodologies resulted necessary to obtain detailed structural information from the enzyme.

Abstract
Capillary electrophoresis coupled to orthogonal accelerated time-of-flight mass spectrometry (CE/TOFMS) was used for the analysis of O- and N-glycopeptides of recombinant human erythropoietin (rhEPO). O(126) and N(83) with a tetraantennary complex type glycan (N(83)-4Ant) were selected as glycopeptide models to develop an optimum CE/TOFMS methodology capable of detecting and characterizing the wide variety of glycopeptides present in the glycoprotein digest. Glycopeptide adsorption in the inner surface of the fused-silica capillary was prevented after using a capillary conditioning of 1 M HAc between runs. On the other hand, different acidic conditions in the sheath liquid (SL) and in the background electrolyte (BGE) were tested with the aim of studying their influence in glycopeptide fragmentation. Finally, the fragmentor voltage value of the TOF-MS instrument was optimized to avoid the involuntary fragmentation of the native glycopeptides. Hence, the established method may be regarded as an excellent starting point to obtain reliable glycopeptide maps of complex glycoproteins such as rhEPO by CE/TOFMS.
