Fig. 3From: BluB/CobT2 fusion enzyme activity reveals mechanisms responsible for production of active form of vitamin B12 by Propionibacterium freudenreichii Alignment of the spacer regions. Part of the multiple sequence alignment of predicted BluB/CobT fusion proteins from different microorganisms showing the region between the BluB (aa 1–257) and CobT (aa 294–626) domains of BluB/CoBT2 of P. freudenreichii. The predicted spacer region is indicated by a line above the amino acid sequence. Protein sequences were obtained from NCBI Protein data base: P. freudenreichii [WP_013160556.1], P. acidifaciens [WP_028706153.1], P. acnes [WP_002548940.1], Propionibacterium humerusii [WP_007433757.1], P. lymphophilium [EPD33903], Blastococcus saxobsidens [WP_014375557.1], Dermacoccus sp. [WP_047312757.1], A. chelonae [WP_006501272.1], Janibacter sp. [WP_009778314.1] and Knoellia sinensis [WP_035916832.1] sequences were aligned by ClustalW and rendered using BOXSHADEBack to article page
