Abstract

Background: Chitinase is an enzyme crucial in chitin biodegradation, breaking the 1,4-N-α-acetyl-D-glucosamine bonds of its monomers. It is produced by a wide range of organisms, from microorganisms such as bacteria and fungi to macroorganisms including humans. Chitinases have been widely studied for applications in biological control, environmental management, and medical fields, including immune modulation and infection therapy. However, there is still a research gap due to the limited number of systematic comparative studies examining the structural, genetic, and functional differences among chitinases from various biological sources. This limitation hinders optimal and targeted use of chitinases in enzyme-based technologies, particularly for medical applications. Therefore, comprehensive studies are needed not only to describe chitinases by their sources but also to evaluate their practical potential and innovative opportunities for human health. Methods: This study uses a narrative literature review approach. Articles were collected, screened, and systematically organized according to their scope, focusing on chitinase sources, mechanisms of action, and applications in healthcare. Results: The analysis shows fundamental differences in domain structure, gene expression, and catalytic mechanisms of chitinases from bacteria, fungi, and humans. Bacterial chitinases exhibit environmental stability and serve as infection biomarkers, fungal chitinases excel in immunotherapy and bioactive compound production, and human chitinases, though less explored, show potential in precision diagnostics and inflammatory therapy. Conclusions: This cross-domain comparison maps structural and functional characteristics and opens opportunities for integrating cross-species enzyme functions for innovative enzyme-based biopharmaceuticals and precision therapies addressing modern pathogens

Abstract

Background: The physical characteristics of soil under different land uses influence its potential for optimal productivity. Wotan Village, located in Panceng District, Gresik Regency (part of the northern limestone mountains), can maximize land use by considering the type of crops and land suitability based on soil physical properties. The mismatch in land use in Wotan Village is likely due to poor soil physical properties, as the soil is formed from weathered limestone. Limestone soils are dominated by fine fractions in their texture, and their texture and structure are generally unsuitable for use as planting media. This study aims to analyze the physical characteristics of soils under various land-use types and to determine the effect of different land uses on soil physical properties. Methodology: The research employed a purposive sampling method. Soil samples were collected from three types of land use: plantation, dryland farming, and rainfed rice fields, at two depths (0-20 cm and 20-40 cm) with five replications. Laboratory analyses were conducted on soil physical parameters, including texture, bulk density, particle density, total pore space, and permeability. Findings: The results showed that the soils in the three land-use types had clay loam, silty clay, and clay textures. Bulk density ranged from 1.10 to 1.24 g/cm³ for rainfed rice fields at a depth of 20 cm. Particle density ranged from 2.46 to 2.603 g/cm³. Total pore space ranged from 52.46% to 56.31%. Permeability ranged between 0.80 and 1.21 cm/hour, classified as moderately slow. Differences in land use had no significant effect on soil physical properties. Contribution: The findings provide a reference for farmers regarding the physical properties of soils in limestone areas
