Agent-Based Modeling Reveals Possible Mechanisms for Observed Aggregation Cell Behaviors.

Myxococcus xanthus is a soil bacterium that serves as a model system for biological self-organization. Cells form distinct, dynamic patterns depending on environmental conditions. An agent-based model was used to understand how M.

An Orphan MbtH-Like Protein Interacts with Multiple Nonribosomal Peptide Synthetases in Myxococcus xanthus DK1622.

One mechanism by which bacteria and fungi produce bioactive natural products is the use of nonribosomal peptide synthetases (NRPSs). Many NRPSs in bacteria require members of the MbtH-like protein (MLP) superfamily for their solubility or function. Although MLPs are known to interact with the adenylation domains of NRPSs, the role MLPs play in NRPS enzymology has yet to be elucidated.

Fatty Acid Oxidation Is Required for Myxococcus xanthus Development.

cells produce lipid bodies containing triacylglycerides during fruiting body development. Fatty acid β-oxidation is the most energy-efficient pathway for lipid body catabolism. In this study, we used mutants in (MXAN_5371 and MXAN_6987) and (MXAN_5372) homologs to examine whether β-oxidation serves an essential developmental function.

Data-driven modeling reveals cell behaviors controlling self-organization during development.

Collective cell movement is critical to the emergent properties of many multicellular systems, including microbial self-organization in biofilms, embryogenesis, wound healing, and cancer metastasis. However, even the best-studied systems lack a complete picture of how diverse physical and chemical cues act upon individual cells to ensure coordinated multicellular behavior. Known for its social developmental cycle, the bacterium uses coordinated movement to generate three-dimensional aggregates called fruiting bodies.
