ABSTRACT Free N-glycans (FNGs) are ubiquitous in growing plants. Further, acidic peptide:N-glycanase is believed to be involved in the production of plant complex-type FNGs (PCT-FNGs) during the degradation of dysfunctional glycoproteins. However, the distribution of PCT-FNGs in growing plants has not been analyzed. Here, we report the occurrence of PCT-FNGs in the xylem sap of the stem of the tomato plant. Abbreviations: RP-HPLC: reversed-phase HPLC; SF-HPLC: size-fractionation HPLC; PA… Expand

Complex N-Glycans Are Important for Normal Fruit Ripening and Seed Development in Tomato
The analyses stress the importance of complex N-glycan maturation for normal plant responses, especially in fruit-bearing crops like tomato, where GNTI-RNA interference plants were more susceptible to sporadic infection. Expand
Determination of complex type free, non‐conjugated oligosaccharide glucose unit values in tomato xylem sap for early detection of nutrient deficiency
The statistical correlation between nutrient (nitrogen) deficiency symptoms of crops and changes in 8‐aminopyrene‐1,3,6‐trisulfonic acid (APTS)‐labeled complex type free oligosaccharides is reported. Expand

Structural features of free N-glycans occurring in plants and functional features of de-N-glycosylation enzymes, ENGase, and PNGase: the presence of unusual plant complex type N-glycans
The findings suggest that endo-β-N-acetylglucosaminidase (ENGase) must be involved in the production of GN1 type FNGs, whereas only peptide:N-glycanase (PNGase) is involved in a plant complex type F NGs, and putative functions of FNGS are also discussed. Expand
Occurrence of Free N-Glycans in Pea (Pisum sativum, L) Seedlings†.
Structural analyses showed that the several oligomannose-type sugar chains having one GlcNAc residue at the reducing-end side occur in the seedlings, suggesting the endo-β-N-acetylgIucosaminidase PS should be involved in the release of oligomANNose- type N-glycans from the storage glycoproteins during the germination of pea seeds.

Intracellular and extracellular free N-glycans produced by plant cells: occurrence of unusual plant complex-type free N-glycans in extracellular spaces.
The structural features of free N-glycans accumulated inside cells and secreted to the extracellular space using a rice cell culture system suggested that two kinds of glycoenzymes, cytosolic endo-β-N-acetylglucosaminidase (ENGase) and intracellular acidic peptide:N-glycanse (PNGase), are involved in the production of FNGs in rice cell as well as in other plant cells.

Free N-glycans already occur at an early stage of seed development.
It is demonstrated that two kinds of free N-glycans already occur at an early stage of seed development, which were determined by a combination of ESI-MS, sequential a-mannosidase digestions, partial acetolysis, and two dimensional sugar chain map. Expand
Molecular identification and characterization of an acidic peptide:N-glycanase from tomato (Lycopersicum esculentum) fruits.
The phylogenetic analysis reveals that the plant acidic PNGase is completely different from the ubiquitous cytosolic PNGase and is involved in a different de-N-glycosylation mechanism associated with plant growth and development. Expand
Structure of Ten Free N-Glycans in Ripening Tomato Fruit (Arabinose Is a Constituent of a Plant N-Glycan)
The finding of free Man5GlcNAc in situ was important physiologically because previously it had been described as a promoter of tomato ripening when added exogenously. Expand
Molecular characterization of plant acidic alpha-mannosidase, a member of glycosylhydrolase family 38, involved in the turnover of N-glycans during tomato fruit ripening.
A molecular 3D modelling shows that catalytically important residues of animal lysosomal α-mannosidase could be superimposed on those of tomato α-mannsidase, suggesting that active site conformation is highly conserved between plant acidic α- Mannsidase and animal l Lysosomalα-mannOSidase. Expand
Structural features of N-glycans linked to glycoproteins expressed in three kinds of water plants: Predominant occurrence of the plant complex type N-glycans bearing Lewis a epitope.
Three water plants, Elodea nuttallii, Egeria densa, and Ceratophyllum demersum, produce glycoproteins bearing Lewis a units, suggesting that these water plants are good sources for preparation of Lewis a type plant N-glycans in substantial amounts. Expand
Subcellular localization of endo-beta-N-acetylglucosaminidase and high-mannose type free N-glycans in plant cell.
The detailed analysis of substrate specificity of endo-CM showed that the pumpkin enzyme were highly active toward the high-mannose type glycans bearing the Man(alpha1)-2Man( alpha1)-3Man(beta1)-structural unit. Expand

Substrate specificity and some other enzymatic properties of partial purified endo-beta-N-acetylglucosaminidases from developing soybean seeds and developing tomato fruits were studied and compared to various pyridylaminated N-glycans derived from some naturally occurring glycoproteins. Expand
