Cold active enzymes or psychrozymes works under cold condition and provide a high specificity and different from the mesophilic counterpart with low thermo-stability and a high specific activity at moderate or lower temperature. A large microbial diversity is able to produce xylanase enzyme that is responsible for the xylan hydrolysis. Degradation of xylan id difficult due its heterogenous nature and which is easily overcome by xylanases. Xylanases are may be grouped under glycoside hydrolase families. To fulfil the commercial or industrial demands, xylanases, which can be used under cold environment are attracting most due to their high efficiency at lower temperature, cost effectiveness in industrial field and sustainability. This article focuses on the characterization of psychrophilic xylanases giving emphasis on protein folding and adaptations. The folding adaptations of psychrophilic xylanases viz. presence of (a/a)6 barrel and (ß/a)8 barrel, lesser number of salt bridges and higher accessible surface area makes them different from other xylanases. Xylanase, acts as an ‘eco-friendly’ tool, isolated from microbial sources show various biochemical properties which make it suitable for various purposes. This present review also emphasises the important role of xylanases in some industries also like animal feed industry, to improve the digestibility; food industry, especially for baking, cheese ripening and also in case of, to reduce heat of a reaction it is used.
