SWATH-MS proteome of Moraxella catarrhalis under iron restricted conditions

Moraxella catarrhalis is a human-restricted bacterial pathogen that causes otitis media in children and exacerbations of chronic obstructive pulmonary disease in adults. Iron is a co-factor required for the function of proteins involved in respiration and DNA replication, and thus is essential to life for most bacterial species. As iron is sequestered by host tissues, all host-adapted pathogens encounter periods of iron starvation. Previous studies have defined the repertoire of genes required for growth of M. catarrhalis under iron restricted conditions, and described differential expression at the transcriptional level. However, global changes in protein expression in response to iron starvation have not been investigated. Here we provide a SWATH-MS dataset describing differential expression of the M. catarrhalis CCRI-195ME proteome under iron restricted versus iron replete conditions.
