TIGR02764	spore_ybaN_pdaB	3.73e-72	49	238	1	191	polysaccharide deacetylase family sporulation protein PdaB. This model describes the YbaN protein family, also called PdaB and SpoVIE, of Gram-positive bacteria. Although ybaN null mutants have only a mild sporulation defect, ybaN/ytrI double mutants show drastically reducted sporulation efficiencies. This synthetic defect suggests the role of this sigmaE-controlled gene in sporulation had been masked by functional redundancy. Members of this family are homologous to a characterized polysaccharide deacetylase; the exact function this protein family is unknown. [Cellular processes, Sporulation and germination]
cd10917	CE4_NodB_like_6s_7s	4.56e-67	54	225	1	171	Catalytic NodB homology domain of rhizobial NodB-like proteins. This family belongs to the large and functionally diverse carbohydrate esterase 4 (CE4) superfamily, whose members show strong sequence similarity with some variability due to their distinct carbohydrate substrates. It includes many rhizobial NodB chitooligosaccharide N-deacetylase (EC 3.5.1.-)-like proteins, mainly from bacteria and eukaryotes, such as chitin deacetylases (EC 3.5.1.41), bacterial peptidoglycan N-acetylglucosamine deacetylases (EC 3.5.1.-), and acetylxylan esterases (EC 3.1.1.72), which catalyze the N- or O-deacetylation of substrates such as acetylated chitin, peptidoglycan, and acetylated xylan. All members of this family contain a catalytic NodB homology domain with the same overall topology and a deformed (beta/alpha)8 barrel fold with 6- or 7 strands. Their catalytic activity is dependent on the presence of a divalent cation, preferably cobalt or zinc, and they employ a conserved His-His-Asp zinc-binding triad closely associated with the conserved catalytic base (aspartic acid) and acid (histidine) to carry out acid/base catalysis. Several family members show diversity both in metal ion specificities and in the residues that coordinate the metal.
cd10950	CE4_BsYlxY_like	7.48e-62	50	238	2	188	Putative catalytic NodB homology domain of uncharacterized protein YlxY from Bacillus subtilis and its bacterial homologs. The Bacillus subtilis genome contains six polysaccharide deacetylase gene homologs: pdaA, pdaB (previously known as ybaN), yheN, yjeA, yxkH and ylxY. This family is represented by Bacillus subtilis putative polysaccharide deacetylase BsYlxY, encoded by the ylxY gene, which is a member of the carbohydrate esterase 4 (CE4) superfamily. Although its biological function still remains unknown, BsYlxY shows high sequence homology to the catalytic domain of Bacillus subtilis pdaB gene encoding a putative polysaccharide deacetylase (BsPdaB), which is essential for the maintenance of spores after the late stage of sporulation and is highly conserved in spore-forming bacteria. However, disruption of the ylxY gene in B. subtilis did not cause any sporulation defect. Moreover, the Asp residue in the classical His-His-Asp zinc-binding motif of CE4 esterases is mutated to a Val residue in this family. Other catalytically relevant residues of CE4 esterases are also not conserved, which suggest that members of this family may be inactive.
cd10949	CE4_BsPdaB_like	5.62e-57	56	238	6	190	Putative catalytic NodB homology domain of Bacillus subtilis putative polysaccharide deacetylase PdaB, and its bacterial homologs. The Bacillus subtilis genome contains six polysaccharide deacetylase gene homologs: pdaA, pdaB (previously known as ybaN), yheN, yjeA, yxkH and ylxY. This family is represented by the putative polysaccharide deacetylase PdaB encoded by the pdaB gene on sporulation of Bacillus subtilis. Although its biochemical properties remain to be determined, the PdaB (YbaN) protein is essential for maintaining spores after the late stage of sporulation and is highly conserved in spore-forming bacteria. The glycans of the spore cortex may be candidate PdaB substrates. Based on sequence similarity, the family members are classified as carbohydrate esterase 4 (CE4) superfamily members. However, the classical His-His-Asp zinc-binding motif of CE4 esterases is missing in this family.
cd10947	CE4_SpPgdA_BsYjeA_like	6.95e-49	56	227	3	170	Catalytic NodB homology domain of Streptococcus pneumoniae peptidoglycan deacetylase PgdA, Bacillus subtilis BsYjeA protein, and their bacterial homologs. This family is represented by Streptococcus pneumoniae peptidoglycan GlcNAc deacetylase (SpPgdA), a member of the carbohydrate esterase 4 (CE4) superfamily. SpPgdA protects gram-positive bacterial cell wall from host lysozymes by deacetylating peptidoglycan N-acetylglucosamine (GlcNAc) residues. It consists of three separate domains: N-terminal, middle and C-terminal (catalytic) domains. The catalytic NodB homology domain is similar to the deformed (beta/alpha)8 barrel fold adopted by other CE4 esterases, which harbors a mononuclear metalloenzyme employing a conserved His-His-Asp zinc-binding triad closely associated with conserved catalytic base (aspartic acid) and acid (histidine) to carry out acid/base catalysis. The enzyme is able to accept GlcNAc3 as a substrate, with the N-acetyl of the middle sugar being removed by the enzyme. This family also includes Bacillus subtilis BsYjeA protein encoded by the yjeA gene, which is one of the six polysaccharide deacetylase gene homologs (pdaA, pdaB/ybaN, yheN, yjeA, yxkH and ylxY) in the Bacillus subtilis genome. Although homology comparison shows that the BsYjeA protein contains a polysaccharide deacetylase domain, and was predicted to be a membrane-bound xylanase or a membrane-bound chitooligosaccharide deacetylase, more recent research indicates BsYjeA might be a novel non-specific secretory endonuclease which creates random nicks progressively on the two strands of dsDNA, resulting in highly distinguishable intermediates/products very different in chemical and physical compositions over time. In addition, BsYjeA shares several enzymatic properties with the well-understood DNase I endonuclease. Both enzymes are active on ssDNA and dsDNA, both generate random nicks, and both require Mg2+ or Mn2+ for hydrolytic activity.
