In this regard<jats:italic>Cupriavidus necator<\/jats:italic>H16 represents a particularly promising microbial chassis due to its ability to grow on a wide range of low-cost feedstocks, including the waste gas carbon dioxide, whilst also naturally producing large quantities of polyhydroxybutyrate (PHB) during nutrient-limited conditions. Understanding the complex metabolic behaviour of this bacterium is a prerequisite for the design of successful engineering strategies for optimising product yields. We present a genome-scale metabolic model (GSM) of<jats:italic>C<\/jats:italic>.<jats:italic>necator<\/jats:italic>H16 (denoted<jats:italic>i<\/jats:italic>CN1361), which is directly constructed from the BioCyc database to improve the readability and reusability of the model. After the initial automated construction, we have performed extensive curation and both theoretical and experimental validation. By carrying out a genome-wide essentiality screening using a Transposon-directed Insertion site Sequencing (TraDIS) approach, we showed that the model could predict gene knockout phenotypes with a high level of accuracy. Importantly, we indicate how experimental and computational predictions can be used to improve model structure and, thus, model accuracy as well as to evaluate potential false positives identified in the experiments. Finally, by integrating transcriptomics data with<jats:italic>i<\/jats:italic>CN1361 we create a condition-specific model, which, importantly, better reflects PHB production in<jats:italic>C<\/jats:italic>.<jats:italic>necator<\/jats:italic>H16. Observed changes in the omics data and<jats:italic>in-silico<\/jats:italic>-estimated alterations in fluxes were then used to predict the regulatory control of key cellular processes. The results presented demonstrate that<jats:italic>i<\/jats:italic>CN1361 is a valuable tool for unravelling the system-level metabolic behaviour of<jats:italic>C<\/jats:italic>.<jats:italic>necator<\/jats:italic>H16 and can provide useful insights for designing metabolic engineering
