N-terminal double-psi beta-barrel fold domain of the beta-expansin subfamily; Beta-expansins (EXPB, expansin-B) have cell wall loosening activity and are involved in cell expansion and other developmental events during which cell wall modification occurs. They also affect environmental stress responses. The EXPB subfamily is known in the allergen literature as group-1 grass pollen allergens. EXPB of Bermuda, Johnson, and Para grass pollens, is a major cross-reactive allergen for allergic rhinitis patients in subtropical climate. EXPB1 induces extension and stress relaxation of grass cell walls. Wheat TaEXPB7-B is a beta-expansin gene involved in low-temperature stress and abscisic acid responses. Beta-expansins belong to the expansin family of proteins that contain an N-terminal domain (D1) homologous to the catalytic domain of glycoside hydrolase family 45 (GH45) proteins but with no hydrolytic activity, and a C-terminal domain (D2) homologous to group-2 grass pollen allergens.

N-terminal double-psi beta-barrel fold domain of bacterial expansins similar to Bacillus subtilis EXLX1; This subfamily is composed of bacterial expansins including Bacillus subtilis EXLX1, also called expansin-YoaJ. Similar to plant expansins, EXLX1 contains an N-terminal domain (D1) homologous to the catalytic domain of glycoside hydrolase family 45 (GH45) proteins but with no hydrolytic activity, and a C-terminal domain (D2) homologous to group-2 grass pollen allergens. It strongly binds to crystalline cellulose via D2, and weakly binds soluble cellooligosaccharides. Bacterial expansins, which are present in some plant pathogens, have the ability to loosen plant cell walls, but with weaker activity compared to plant expansins. They may have a role in plant-bacterial interactions. This model represents the N-terminal domain of EXLX1 and similar bacterial expansins, which adopts a double-psi beta-barrel (DPBB) fold.

N-terminal double-psi beta-barrel fold domain of the expansin-like A subfamily; Expansin-like A (EXLA) belongs to the plant expansin family that also includes alpha-expansin (EXPA), beta-expansin (EXPB), and expansin-like B (EXLB). Unlike EXPA and EXPB, EXLA proteins have not been shown to display cell wall loosening activity. EXLA2 is one of the three EXLA members in Arabidopsis. It lacks expansin activity, but contains a presumed cellulose-interacting domain. EXLA2 may function as a positive regulator of cell elongation in the dark-grown hypocotyl of Arabidopsis, possibly by interference with cellulose metabolism, deposition, or its organization. EXLA belongs to the expansin family of proteins that contain an N-terminal domain (D1) homologous to the catalytic domain of glycoside hydrolase family 45 (GH45) proteins but with no hydrolytic activity, and a C-terminal domain (D2) homologous to group-2 grass pollen allergens.

double-psi beta-barrel fold of EG45-like domain-containing proteins; This family contains plant EG45-like domain-containing proteins which show sequence similarity to expansins, and similar proteins. Citrus jambhiri EG45-like domain-containing protein was identified as a protein associated with citrus blight (CB), and is also called blight-associated protein p12 (CjBAp12) or plant natriuretic peptide (PNP). CjBAp12 does not display cell wall loosening activity of expansins. Arabidopsis thaliana EG45-like domain-containing protein 2, also called plant natriuretic peptide A (AtPNP-A), is a systemically mobile natriuretic peptide immunoanalog, recognized by antibodies against vertebrate atrial natriuretic peptides (ANPs), that functions in cell volume regulation. Thus, it has an important and systemic role in plant growth and homeostasis. Due to their similarity to the N-terminal domain of expansin and to endolytic peptidoglycan transglycosylase RlpA, EG45-like domain-containing proteins may adopt a double-psi beta-barrel fold.

double-psi beta-barrel fold of RlpA, N-terminal domain of expansins, and similar domains; The double-psi beta-barrel (DPBB) fold is found in a divergent group of proteins, including endolytic peptidoglycan transglycosylase RlpA (rare lipoprotein A), EG45-like domain containing proteins, kiwellins, Streptomyces papain inhibitor (SPI), the N-terminal domain of plant and bacterial expansins, GH45 family of endoglucanases, barwins, cerato-platanins, membrane-bound lytic murein transglycosylase A (MltA) and YuiC-like proteins. RlpA may work in tandem with amidases to degrade peptidoglycan (PG) in the division septum and lateral wall to facilitate daughter cell separation. An EG45-like domain containing protein from Arabidopsis thaliana, called plant natriuretic peptide A (AtPNP-A), functions in cell volume regulation. Kiwellin proteins comprise a widespread family of plant-defense proteins that target pathogenic bacterial/fungal effectors that down-regulate plant defense responses. SPI is a stress protein produced under hyperthermal stress conditions that serves as a glutamine and lysine donor substrate for microbial transglutaminase (MTG, EC 2.3.2.13) from Streptomycetes. Some expansin family proteins display cell wall loosening activity and are involved in cell expansion and other developmental events during which cell wall modification occurs. Endoglucanases (EC 3.2.1.4) catalyze the endohydrolysis of (1-4)-beta-D-glucosidic linkages in cellulose, lichenin, and cereal beta-D-glucans. Animal cellulases, such as endoglucanase EG27II, have great potential for industrial applications such as bioethanol production. Barwin is a basic protein from barley seed. It is a probable plant lectin that may be involved in a defense mechanism. Cerato-platanin is a phytotoxin which causes production of phytoalexin in platanus acerifolia, platanus occidentalis, and platanus orientalis. It also induces cell necrosis. MltA, also called murein hydrolase A, is a murein-degrading enzyme that may play a role in recycling of muropeptides during cell elongation and/or cell division. It degrades murein glycan strands and insoluble, high-molecular weight murein sacculi. YuiC is a Firmicute stationary phase survival (Sps) protein.
