abstract = {Compartmentalization represents a ubiquitous principle used
by living organisms to optimize metabolic flux and to avoid
detrimental interactions within the cytoplasm. Proteinaceous
bacterial microcompartments (BMCs) have therefore created
strong interest for the encapsulation of heterologous
pathways in microbial model organisms. However, attempts
were so far mostly restricted to Escherichia coli. Here, we
introduced the carboxysomal gene cluster of Halothiobacillus
neapolitanus into the biotechnological platform species
Corynebacterium gluta-micum. Transmission electron
microscopy, fluorescence microscopy and single molecule
localization microscopy suggested the formation of BMC-like
structures in cells expressing the complete carboxysome
operon or only the shell proteins. Purified carboxysomes
consisted of the expected protein components as verified by
mass spectrometry. Enzymatic assays revealed the functional
production of RuBisCO in C. glutamicum both in the presence
and absence of carboxysomal shell proteins. Furthermore, we
could show that eYFP is targeted to the carboxysomes by
fusion to the large RuBisCO subunit. Overall, this study
represents the first transfer of an α‐carboxysomal gene
cluster into a Gram-positive model species supporting the
modularity and orthogonality of these microcompartments, but
also identified important challenges which need to be
addressed on the way towards biotechnological application.},
