Structural Determinants Responsible for Substrate Recognition and Mode of Action in Family 11 Polysaccharide Lyases [PDF]
Journal of Biological Chemistry, 2009 A saprophytic Bacillus subtilis secretes two types of rhamnogalacturonan (RG) lyases, endotype YesW and exotype YesX, which are responsible for an initial cleavage of the RG type I (RG-I) region of plant cell wall pectin. Polysaccharide lyase family 11 YesW and YesX with a significant sequence identity (67.8%) cleave glycoside bonds between rhamnose ...

Crystal Structure of Family 14 Polysaccharide Lyase with pH-dependent Modes of Action [PDF]
Journal of Biological Chemistry, 2009 The Chlorella virus enzyme vAL-1 (38 kDa), a member of polysaccharide lyase family 14, degrades the Chlorella cell wall by cleaving the glycoside bond of the glucuronate residue (GlcA) through a beta-elimination reaction. The enzyme consists of an N-terminal cell wall-attaching domain (11 kDa) and a C-terminal catalytic module (27 kDa).

Gellan lyases-novel polysaccharide lyases [PDF]
Microbiology, 1994 A number of bacterial strains capable of degrading the bacterial exopolysaccharide gellan have been isolated by standard enrichment procedures. They include several pink-pigmented Gram-negative rod-shaped bacteria. A red-pigmented Gram-positive bacillus earlier found to degrade the exopolysaccharide xanthan from Xanthomonas campestris also showed ...

Structural insights into the mechanism of pH-selective substrate specificity of the polysaccharide lyase Smlt1473 [PDF]
Journal of Biological Chemistry, 2021 Polysaccharide lyases (PLs) are a broad class of microbial enzymes that degrade anionic polysaccharides. Equally broad diversity in their polysaccharide substrates has attracted interest in biotechnological applications such as biomass conversion to value-added chemicals and microbial biofilm removal.

Phylogenetic Distribution of Polysaccharide-Degrading Enzymes in Marine Bacteria
Frontiers in Microbiology, 2021 Deconstruction is an essential step of conversion of polysaccharides, and polysaccharide-degrading enzymes play a key role in this process. Although there is recent progress in the identification of these enzymes, the diversity and phylogenetic ...

Genome-Wide Analysis of PL7 Alginate Lyases in the Genus Zobellia
Molecules, 2021 We carried out a detailed investigation of PL7 alginate lyases across the Zobellia genus. The main findings were obtained using the methods of comparative genomics and spatial structure modeling, as well as a phylogenomic approach. Initially, in order to

Polysaccharide lyases from gellan-producing Sphingomonas spp. [PDF]
Microbiology, 1996 A number ofSphingomonasstrains capable of synthesizing the bacterial exopolysaccharide gellan and related polymers were shown to possess constitutive gellanase activity. In each case, the degradation of deacylated gellan was due to extracellular, eliminase-type enzymes (lyases) which cleave the sequence …ß-D-glucosyl 1,4-ß-D-glucuronosyl… in the ...
