L polysaccharide-degrading enzymes of S. hirsutum, N. aurantialba has practically no
L polysaccharide-degrading enzymes of S. hirsutum, N. aurantialba has practically no oxidoreductase (AA3, AA8, and AA9), cellulosedegrading enzymes (GH6, GH7, GH12, and GH44), hemicellulose-degrading enzymes (GH10, GH11, GH12, GH27, GH35, GH74, GH93, and GH95), and pectinase (GH93, PL1, PL3, and PL4). It was shown that N. aurantialba features a low variety of genes identified within the genome to degrade plant cell wall polysaccharides (cellulose, hemicellulose, and pectin), whereas S. hirsutum has a powerful ability to disintegrate. Hence, we speculated that S. hirsutum CETP web hydrolyzed plant cell polysaccharides into cellobiose or glucose for the development and development of N. aurantialba for the duration of cultivation [66]. The CAZyme annotation can present a reference not merely for the analysis of polysaccharidedegrading enzyme lines but also for the analysis of polysaccharide synthetic capacity. A total of 35 genes associated with the synthesis of fungal cell walls (chitin and glucan) had been identified (Table S5). three.five.5. The Cytochromes P450 (CYPs) Loved ones The cytochrome P450s (CYP450) household is a superfamily of ferrous heme thiolate proteins which can be involved in physiological processes, which includes detoxification, xenobiotic degradation, and biosynthesis of secondary metabolites [67]. The KEGG analysis showed that N. aurantialba has four and 4 genes in “metabolism of xenobiotics by cytochrome P450” and “drug metabolism–cytochrome P450”, respectively (Table S6). For further analysis, the CYP loved ones of N. aurantialba was predicted utilizing the databases (Table S6). The outcomes showed that N. aurantialba consists of 26 genes, with only four class CYPs, which can be significantly reduced than that of wood rot fungi, for example S. hirsutum (536 genes). Interestingly, Akapo et al. located that T. mesenterica (eight genes) and N. encephala (ten genes) from the Tremellales had reduced numbers of CYPs [65]. This phenomenon was most likely attributed to the parasitic life style of fungi in the Tremellales, whose ecological niches are wealthy in simple-source organic nutrients, losing a considerable quantity throughout long-term adaptation for the host-derived simple-carbonsource CYPs, thereby compressing genome size [65,68]. Intriguingly, the same phenomenon has been observed in fungal species belonging towards the subphylum Saccharomycotina, exactly where the niche is highly enriched in simple organic nutrients [69]. three.6. Secondary Metabolites In the fields of contemporary food nutrition and pharmacology, mushrooms have attracted substantially interest as a result of their abundant secondary metabolites, which have already been shown to possess many COX-2 site bioactive pharmacological properties, such as immunomodulatory, antiinflammatory, anti-aging, antioxidant, and antitumor [70]. A total of 215 classes of enzymes involved in “biosynthesis of secondary metabolites” (KO 01110) had been predicted, as shown in Table S7. As shown in Table S8, 5 gene clusters (45 genes) potentially involved in secondary metabolite biosynthesis have been predicted. The predicted gene cluster included a single betalactone, two NRPS-like, and two terpenes. No PKS synthesis genes had been located in N. aurantialba, which was constant with most Basidiomycetes. Saponin was extracted from N. aurantialba applying a hot water extraction strategy, which had a much better hypolipidemic influence [71]. The phenolic and flavonoid of N. aurantialba was extracted making use of an organic solvent extraction technique, which revealed sturdy antioxidant activity [10,72]. Hence, this discovering suggests that N. aurantialba has the prospective.
