| contents | Collaborative metabolic curation of an emerging model marine bacterium, Alteromonas macleodii ATCC 27126. Sher, Daniel George, Emma E Wietz, Matthias Gifford, Scott Zoccarato, Luca Weissberg, Osnat Koedooder, Coco Valiya Kalladi, Waseem Bashir Barreto Filho, Marcelo M Mireles, Raul Malavin, Stas Liddor Naim, Michal Idan, Tal Shrivastava, Vibhaw Itelson, Lynne Sade, Dagan Abu Hamoud, Alhan Soussan-Farhat, Yara Barak, Noga Karp, Peter Moore, Lisa R Alteromonas Metabolic Networks and Pathways Nitrogen Carbon Aquatic Organisms Genome, Bacterial Computational Biology Inferring the metabolic capabilities of an organism from its genome is a challenging process, relying on computationally-derived or manually curated metabolic networks. Manual curation can correct mistakes in the draft network and add missing reactions based on the literature, but requires significant expertise and is often the bottleneck for high-quality metabolic reconstructions. Here, we present a synopsis of a community curation workshop for the model marine bacterium Alteromonas macleodii ATCC 27126 and its genome database in BioCyc, focusing on pathways for utilizing organic carbon and nitrogen sources. Due to the scarcity of biochemical information or gene knock-outs, the curation process relied primarily on published growth phenotypes and bioinformatic analyses, including comparisons with related Alteromonas strains. We report full pathways for the utilization of the algal polysaccharides alginate and pectin in contrast to inconclusive evidence for one-carbon metabolism and mixed acid fermentation, in accordance with the lack of growth on methanol and formate. Pathways for amino acid degradation are ubiquitous across Alteromonas macleodii strains, yet enzymes in the pathways for the degradation of threonine, tryptophan and tyrosine were not identified. Nucleotide degradation pathways are also partial in ATCC 27126. We postulate that demonstrated growth on nitrate as sole nitrogen source proceeds via a nitrate reductase pathway that is a hybrid of known pathways. Our evidence highlights the value of joint and interactive curation efforts, but also shows major knowledge gaps regarding Alteromonas metabolism. The manually-curated metabolic reconstruction is available as a "Tier-2" database on BioCyc. |
