Study of carbohydrate-active enzymes (CAZymes) can reveal information about the lifestyle and behavior of an organism. Rhodococcus species is well known for xenobiotic metabolism; however, their carbohydrate utilization ability has been less discussed till date. This study aimed to present the CAZyme analysis of two Rhodococcus strains, PAMC28705 and PAMC28707, isolated from lichens in Antarctica, and compare them with other Rhodococcus, Mycobacterium, and Corynebacterium strains. Genome-wide computational analysis was performed using various tools. Results showed similarities in CAZymes across all the studied genera. All three genera showed potential for significant polysaccharide utilization, including starch, cellulose, and pectin referring their biotechnological potential. Keeping in mind the pathogenic strains listed across all three genera, CAZymes associated to pathogenicity were analyzed too. Cutinase enzyme, which has been associated with phytopathogenicity, was abundant in all the studied organisms. CAZyme gene cluster of Rhodococcus sp. PAMC28705 and Rhodococcus sp. PAMC28707 showed the insertion of cutinase in the cluster, further supporting their possible phytopathogenic properties.

红球菌属的完整基因组测序和比较 CAZyme 分析。PAMC28705 和 PAMC28707 深入了解它们的生物技术和植物致病潜力

碳水化合物活性酶 (CAZymes) 的研究可以揭示有关生物体生活方式和行为的信息。红球菌属物种以异生物质代谢而闻名。然而，迄今为止，它们的碳水化合物利用能力鲜有讨论。本研究旨在展示从南极洲地衣中分离的两种红球菌菌株 PAMC28705 和 PAMC28707 的 CAZyme 分析，并将它们与其他红球菌、分枝杆菌和棒状杆菌菌株进行比较。使用各种工具进行全基因组计算分析。结果显示所有研究属中 CAZymes 的相似性。所有三个属都显示出可显着利用多糖的潜力，包括淀粉、纤维素和果胶，它们都具有生物技术潜力。牢记所有三个属中列出的致病菌株，与致病性相关的 CAZymes 也进行了分析。与植物致病性有关的角质酶在所有研究的生物体中含量丰富。红球菌属的 CAZyme 基因簇。PAMC28705 和红球菌属。PAMC28707 显示了角质酶在簇中的插入，进一步支持了它们可能的植物致病特性。
