cd10969 CE4_Ecf1_like_5s 7.87e-68 25 371 1 218
Putative catalytic NodB homology domain of a hypothetical protein Ecf1 from Escherichia coli and similar proteins. This family contains a hypothetical protein Ecf1 from Escherichia coli and its prokaryotic homologs. Although their biochemical properties remain to be determined, members in this family contain a conserved domain with a 5-stranded beta/alpha barrel, which is similar to the catalytic NodB homology domain of rhizobial NodB-like proteins, belonging to the larger carbohydrate esterase 4 (CE4) superfamily.
cd10918 CE4_NodB_like_5s_6s 2.81e-22 62 340 1 138
Putative catalytic NodB homology domain of PgaB, IcaB, and similar proteins which consist of a deformed (beta/alpha)8 barrel fold with 5- or 6-strands. 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 bacterial poly-beta-1,6-N-acetyl-D-glucosamine N-deacetylase PgaB, hemin storage system HmsF protein in gram-negative species, intercellular adhesion proteins IcaB, and many uncharacterized prokaryotic polysaccharide deacetylases. It also includes a putative polysaccharide deacetylase YxkH encoded by the Bacillus subtilis yxkH gene, which is one of six polysaccharide deacetylase gene homologs present in the Bacillus subtilis genome. Sequence comparison shows all family members contain a conserved domain similar to the catalytic NodB homology domain of rhizobial NodB-like proteins, which consists of a deformed (beta/alpha)8 barrel fold with 6 or 7 strands. However, in this family, most proteins have 5 strands and some have 6 strands. Moreover, long insertions are found in many family members, whose function remains unknown.
TIGR03938 deacetyl_PgaB 4.09e-22 4 336 1 228
poly-beta-1,6-N-acetyl-D-glucosamine N-deacetylase PgaB. Two well-characterized systems produce polysaccharide based on N-acetyl-D-glucosamine in straight chains with beta-1,6 linkages. These are encoded by the icaADBC operon in Staphylococcus species, where the system is designated polysaccharide intercellular adhesin (PIA), and the pgaABCD operon in Gram-negative bacteria such as E. coli. Both systems include a putative polysaccharide deacetylase. The PgaB protein, described here, contains an additional domain lacking from its Gram-positive counterpart IcaB (TIGR03933). Deacetylation by this protein appears necessary to allow export through the porin PgaA [Cell envelope, Biosynthesis and degradation of surface polysaccharides and lipopolysaccharides]
cd10964 CE4_PgaB_5s 2.23e-18 58 336 1 170
N-terminal putative catalytic polysaccharide deacetylase domain of bacterial poly-beta-1,6-N-acetyl-D-glucosamine N-deacetylase PgaB, and similar proteins. This family is represented by an outer membrane lipoprotein, poly-beta-1,6-N-acetyl-D-glucosamine N-deacetylase (PgaB, EC 3.5.1.-), encoded by Escherichia coli pgaB gene from the pgaABCD (formerly ycdSRQP) operon, which affects biofilm development by promoting abiotic surface binding and intercellular adhesion. PgaB catalyzes the N-deacetylation of poly-beta-1,6-N-acetyl-D-glucosamine (PGA), a biofilm adhesin polysaccharide that stabilizes biofilms of E. coli and other bacteria. PgaB contains an N-terminal NodB homology domain with a 5-stranded beta/alpha barrel, and a C-terminal carbohydrate binding domain required for PGA N-deacetylation, which may be involved in binding to unmodified poly-beta-1,6-GlcNAc and assisting catalysis by the deacetylase domain. This family also includes several orthologs of PgaB, such as the hemin storage system HmsF protein, encoded by Yersinia pestis hmsF gene from the hmsHFRS operon, which is essential for Y. pestis biofilm formation. Like PgaB, HmsF is an outer membrane protein with an N-terminal NodB homology domain, which is likely involved in the modification of the exopolysaccharide (EPS) component of the biofilm. HmsF also has a conserved but uncharacterized C-terminal domain that is present in other HmsF-like proteins in Gram-negative bacteria. This alignment model corresponds to the N-terminal NodB homology domain.
