Abstract

Carrageenan, the major carbohydrate component of some red algae, is an important renewable bioresource with very large annual outputs. Different types of carrageenolytic enzymes in the carrageenan metabolic pathway are potentially valuable for the production of carrageenan oligosaccharides, biofuel, and other chemicals obtained from carrageenan. However, these enzymes are not well-developed for oligosaccharide or biofuel production. For further application, comprehensive knowledge of carrageenolytic enzymes is essential. Therefore, in this review, we first summarize various carrageenolytic enzymes, including the recently discovered β-carrageenase, carrageenan-specific sulfatase, exo-α-3,6-anhydro-D-galactosidase (D-ADAGase), and exo-β-galactosidase (BGase), and describe their enzymatic characteristics. Subsequently, the carrageenan metabolic pathways are systematically presented and applications of carrageenases and carrageenan oligosaccharides are illustrated with examples. Finally, this paper discusses critical aspects that can aid researchers in constructing cascade catalytic systems and engineered microorganisms to efficiently produce carrageenan oligosaccharides or other value-added chemicals through the degradation of carrageenan. Overall, this paper offers a comprehensive overview of carrageenolytic enzymes, providing valuable insights for further exploration and application of these enzymes.

关于角叉菜溶解酶的系统综述:从代谢途径到生物技术应用
卡拉胶是一些红藻的主要碳水化合物成分,是一种重要的可再生生物资源,年产量非常大。卡拉胶代谢途径中不同类型的卡拉胶分解酶对生产卡拉胶低聚糖、生物燃料和从卡拉胶中提取的其他化学品具有潜在价值。然而,这些酶在低聚糖或生物燃料生产方面还没有得到很好的开发。为了进一步应用,必须全面了解卡拉胶分解酶。因此,在这篇综述中,我们首先总结了各种卡拉胶分解酶,包括最近发现的β-卡拉胶酶、卡拉胶特异性硫酸酯酶、外-α-3,6-脱水-D-半乳糖苷酶(D-ADAGase)和外-β-半乳糖苷酶(BGase),并描述了它们的酶学特性。随后,系统介绍了卡拉胶的代谢途径,并举例说明了卡拉胶酶和卡拉胶低聚糖的应用。最后,本文讨论了有助于研究人员构建级联催化系统和工程微生物的关键方面,以便通过降解卡拉胶高效生产卡拉胶低聚糖或其他增值化学品。总之,本文全面概述了卡拉胶分解酶,为进一步探索和应用这些酶提供了宝贵的见解。
