The O-specific polysaccharide lyase from the phage LKA1 tailspike reduces Pseudomonas virulence [PDF]

Scientific Reports, 2017
AbstractPseudomonas phage LKA1 of the subfamily Autographivirinae encodes a tailspike protein (LKA1gp49) which binds and cleaves B-band LPS (O-specific antigen, OSA) of Pseudomonas aeruginosa PAO1. The crystal structure of LKA1gp49 catalytic domain consists of a beta-helix, an insertion domain and a C-terminal discoidin-like domain.

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

Cloning and characterization of a pectin lyase gene from Colletotrichum lindemuthianum and comparative phylogenetic/structural analyses with genes from phytopathogenic and saprophytic/opportunistic microorganisms

BMC Microbiology, 2011
Background Microorganisms produce cell-wall-degrading enzymes as part of their strategies for plant invasion/nutrition. Among these, pectin lyases (PNLs) catalyze the depolymerization of esterified pectin by a β-elimination mechanism.

Structural And Functional Characterization Of Ulvan Degrading Polysaccharide Lyase Enzymes

The FASEB Journal, 2018
Ulvans are the sulfated cell wall polysaccharide present in marine green algae. Ulvan polysaccharides are composed mainly of 3‐sulfated rhamnose, glucuronic acid, iduronic acid and xylose. The sulfation pattern in ulvan resemble glycosaminoglycans in vertebrates.

Degradation of Alginate by a Newly Isolated Marine Bacterium Agarivorans sp. B2Z047

Marine Drugs, 2022
Alginate is the main component of brown algae, which is an important primary production in marine ecosystems and represents a huge marine biomass. The efficient utilization of alginate depends on alginate lyases to catalyze the degradation, and remains ...

Characterization of a Novel Polysaccharide Lyase Family 5 Alginate Lyase with PolyM Substrate Specificity

Foods, 2022
Alginate lyases (ALyases) have been widely applied in enzymatically degrading alginate for the preparation of alginate oligosaccharides (AOS), which possess a range of excellent physiological benefits including immunoregulatory, antivirus, and antidiabetic properties.

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

Grassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...
