Mass spectrometry has played an integral role in the identification of proteins and their post-
translational modifications (PTM). However, analysis of some PTMs, such as …

Methanobactins (mbs) are low-molecular-mass (< 1,200 Da) copper-binding peptides, or
chalkophores, produced by many methane-oxidizing bacteria (methanotrophs). These …

Mass spectrometry (MS) is a powerful tool to analyze complex mixtures of proteins in a high‐
throughput fashion. Proteome analysis has already become a routine task in biomedical …

Proper development of the mammalian brain requires the precise integration of numerous
temporally and spatially regulated stimuli. Many of these signals transduce their cues via the …

Despite major advantages in the field of proteomics, the analysis of PTMs still poses a major
challenge; thus far, preventing insights into the role and regulation of protein networks …

Integration of inorganic sulfate into biological molecules plays an important role in biological
systems and is directly involved in the instigation of diseases. Protein tyrosine sulfation …

Protein phosphorylation serves as a primary mechanism of signal transduction in the cells of
biological organisms. Technical advancements over the last several years in mass …

Diatoms are abundant unicellular microalgae, responsible for≈ 20% of global
photosynthetic CO2 fixation. Nevertheless, we know little about fundamental aspects of their …

Copper-binding metallophores, or chalkophores, play a role in microbial copper
homeostasis that is analogous to that of siderophores in iron homeostasis. The best-studied …

Post-translational modifications (PTMs) endow proteins with new properties to respond to
environmental changes or growth needs. With the development of advanced proteomics …
