401282	RhgB_N	7.37e-140	22	270	1	251	Rhamnogalacturonan lyase B, N-terminal. Members of this family are found in both fungi, bacteria and wood-eating arthropods. The domain is found at the N-terminus of rhamnogalacturonase B, a member of the polysaccharide lyase family 4. The domain adopts a structure consisting of a beta super-sandwich, with eighteen strands in two beta-sheets. The three domains of the whole protein rhamnogalacturonan lyase (RGL4), are involved in the degradation of rhamnogalacturonan-I, RG-I, an important pectic plant cell-wall polysaccharide. The active-site residues are a lysine at position 169 in UniProtKB:Q00019 and a histidine at 229, Lys169 is likely to be a proton abstractor, His229 a proton donor in the mechanism. The substrate is a disaccharide, and RGL4, in contrast to other rhamnogalacturonan hydrolases, cleaves the alpha-1,4 linkages of RG-I between Rha and GalUA through a beta-elimination resulting in a double bond in the nonreducing GalUA residue, and is thus classified as a polysaccharide lyase (PL).
405384	CBM-like	5.27e-62	361	526	1	157	Polysaccharide lyase family 4, domain III. CBM-like is domain III of rhamnogalacturonan lyase (RG-lyase). The full-length protein specifically recognizes and cleaves alpha-1,4 glycosidic bonds between l-rhamnose and d-galacturonic acids in the backbone of rhamnogalacturonan-I, a major component of the plant cell wall polysaccharide, pectin. This domain possesses a jelly roll beta-sandwich fold structurally homologous to carbohydrate binding modules (CBMs), and it carries two sulfate ions and a hexa-coordinated calcium ion.
199905	RGL4_C	2.74e-60	363	527	1	161	C-terminal domain of rhamnogalacturonan lyase, a family 4 polysaccharide lyase. The rhamnogalacturonan lyase of the polysaccharide lyase family 4 (RGL4) is involved in the degradation of RG (rhamnogalacturonan) type-I, an important pectic plant cell wall polysaccharide, by cleaving the alpha-1,4 glycoside bond between L-rhamnose and D-galacturonic acids in the backbone of RG type-I through a beta-elimination reaction. RGL4 consists of three domains, an N-terminal catalytic domain, a middle domain with a FNIII type fold and a C-terminal domain with a jelly roll fold. Both the middle and the C-terminal domain are putative carbohydrate binding modules. There are two types of RG lyases, which both cleave the alpha-1,4 bonds of the RG-I main chain (RG chain) through the beta-elimination reaction, but belong to two structurally unrelated polysaccharide lyase (PL) families, 4 and 11.
199907	RGL4_N	2.29e-56	22	257	1	265	N-terminal catalytic domain of rhamnogalacturonan lyase, a family 4 polysaccharide lyase. The rhamnogalacturonan lyase of the polysaccharide lyase family 4 (RGL4) is involved in the degradation of RG (rhamnogalacturonan) type-I, an important pectic plant cell wall polysaccharide, by cleaving the alpha-1,4 glycoside bond between L-rhamnose and D-galacturonic acids in the backbone of RG type-I through a beta-elimination reaction. RGL4 consists of three domains, an N-terminal catalytic domain, a middle domain with a FNIII type fold and a C-terminal domain with a jelly roll fold; the middle and C-terminal domains are both putative carbohydrate binding modules. There are two types of RG lyases, which both cleave the alpha-1,4 bonds of the RG-I main chain (RG chain) through the beta-elimination reaction, but belong to two structurally unrelated polysaccharide lyase (PL) families, 4 and 11.
405387	fn3_3	1.79e-21	276	349	1	74	Polysaccharide lyase family 4, domain II. FnIII-like is domain II of rhamnogalacturonan lyase (RG-lyase). The full-length protein specifically recognizes and cleaves alpha-1,4 glycosidic bonds between l-rhamnose and d-galacturonic acids in the backbone of rhamnogalacturonan-I, a major component of the plant cell wall polysaccharide, pectin. This domain displays an immunoglobulin-like or more specifically Fibronectin-III type fold and shows highest structural similarity to the C-terminal beta-sandwich subdomain of the pro-hormone/propeptide processing enzyme carboxypeptidase gp180 from duck. It serves to assist in producing the deep pocket, with domain III, into which the substrate fits.
