The reducing end of cell wall oligosaccharides is critical for DAMP activity in Arabidopsis thaliana and can be exploited by oligosaccharide oxidases in the reduction of oxidized phenolics
Giovannoni M, Scortica A, Scafati V, Piccirilli E, Sorio D, Benedetti M, et al.
Plant Physiol Biochem . 2025 Jan; 220:109466. PMID: 39793330
The enzymatic hydrolysis of cell wall polysaccharides results in the production of oligosaccharides with nature of damage-associated molecular patterns (DAMPs) that are perceived by plants as danger signals. The in...

The Vacuolar H-ATPase subunit C is involved in oligogalacturonide (OG) internalization and OG-triggered immunity
Giovannoni M, Scafati V, Rodrigues Pousada R, Benedetti M, De Lorenzo G, Mattei B
Plant Physiol Biochem . 2024 Sep; 216:109117. PMID: 39293143
In plants, the perception of cell wall fragments initiates signal transduction cascades that activate the immune response. Previous research on early protein dynamics induced by oligogalacturonides (OGs), pectin fragments acting...

Radical cation scavenging activity of berberine bridge enzyme-like oligosaccharide oxidases acting on short cell wall fragments
Scortica A, Scafati V, Giovannoni M, Benedetti M, Mattei B
Sci Rep . 2023 Mar; 13(1):4123. PMID: 36914850
Oligogalacturonide-oxidases (OGOXs) and cellodextrin-oxidase (CELLOX) are plant berberine bridge enzyme-like oligosaccharide-oxidases (OSOXs) that oxidize, respectively, oligogalacturonides (OGs) and cellodextrins (CDs), thereby inactivating their elicitor nature and concomitantly releasing HO. Little...

Characterization of two 1,3-β-glucan-modifying enzymes from Penicillium sumatraense reveals new insights into 1,3-β-glucan metabolism of fungal saprotrophs
Scafati V, Troilo F, Ponziani S, Giovannoni M, Scortica A, Pontiggia D, et al.
Biotechnol Biofuels Bioprod . 2022 Dec; 15(1):138. PMID: 36510318
Background: 1,3-β-glucan is a polysaccharide widely distributed in the cell wall of several phylogenetically distant organisms, such as bacteria, fungi, plants and microalgae. The presence of highly active 1,3-β-glucanases in...

Berberine Bridge Enzyme-like Oligosaccharide Oxidases Act as Enzymatic Transducers Between Microbial Glycoside Hydrolases and Plant Peroxidases
Scortica A, Giovannoni M, Scafati V, Angelucci F, Cervone F, De Lorenzo G, et al.
Mol Plant Microbe Interact . 2022 Jun; 35(10):881-886. PMID: 35704684
Oligogalacturonide (OG)-oxidase 1 (OGOX1) and cellodextrin (CD)-oxidase (CELLOX) are plant berberine bridge enzyme-like oligosaccharide oxidases that oxidize OGs and CDs, cell-wall fragments with the nature of damage-associated molecular patterns. The...

A molecular dynamics-guided mutagenesis identifies two aspartic acid residues involved in the pH-dependent activity of OG-OXIDASE 1
Scortica A, Capone M, Narzi D, Frezzini M, Scafati V, Giovannoni M, et al.
Plant Physiol Biochem . 2021 Nov; 169:171-182. PMID: 34800821
During the infection, plant cells secrete different OG-oxidase (OGOX) paralogs, defense flavoproteins that oxidize the oligogalacturonides (OGs), homogalacturonan fragments released from the plant cell wall that act as Damage Associated...
