“…For enzymes with strong intermolecular interactions, structural rearrangements do not contribute significantly to the adsorption process. Such enzymes are easily adsorbed on hydrophobic surfaces; however, they can adsorb on hydrophilic surfaces only if they are electrostatically attracted (Krisdhasima et al 1992, Norde, 1986, 2003.…”

A b s t r a c t. A majority of biochemical reactions are often catalysed by different types of enzymes. Adsorption of the enzyme is an imperative phenomenon, which protects it from physical or chemical degradation resulting in enzyme reserve in soil. This article summarizes some of the key results from previous studies and provides information about how enzymes are adsorbed on the surface of the soil solid phase and how different factors affect enzymatic activity in soil. Many studies have been done separately on the soil enzymatic activity and adsorption of enzymes on solid surfaces. However, only a few studies discuss enzyme adsorption on soil perspective; hence, we attempted to facilitate the process of enzyme adsorption specifically on soil surfaces. This review is remarkably unmatched, as we have thoroughly reviewed the relevant publications related to protein adsorption and enzymatic activity. Also, the article focuses on two important aspects, adsorption of enzymes and factors limiting the activity of adsorbed enzyme, together in one paper. The first part of this review comprehensively lays emphasis on different interactions between enzymes and the soil solid phase and the kinetics of enzyme adsorption. In the second part, we encircle various factors affecting the enzymatic activity of the adsorbed enzyme in soil.

“…The refractive index gives information about the compactness and hydration of the protein layer, whereas its thickness is related to the molecular dimensions and hence suggests possible orientations or restructuring of the adsorbed molecules. Unfortunately, in most of the ellipsometric studies reported so far only the adsorbed amount was monitored as a function of the different variables mentioned previously and very low attention was paid to the concomitant changes in the refractive index and layer thickness, with the consequent loss of valuable information about the system studied (23)(24)(25)(26). In the cases where the thickness and refractive index have been calculated together with the adsorbed amount, side-on orientation, end-on orientation, surface restructuring, bilayer formation, and multilayer formation have been proposed in order to explain the experimental data (22,27,28).…”

“…Experimental techniques that directly provide information about changes in the secondary structure include ATR-IR [108,111,112] and CD spectroscopy [53,91,104,113] whereas the elution properties are amenable through adsorption and desorption kinetics. Significant conformational changes of a protein are usually slow processes since often a whole cascade of angular rotations takes place [114][115][116][117]. Many proteins initially bind loosely on the surface and only increase their surface affinity afterwards in time by structural changes.…”

Protein adsorption at solid surfaces plays a key role in many natural processes and has therefore promoted a widespread interest in many research areas. Despite considerable progress in this field there are still widely differing and even contradictive opinions on how to explain the frequently observed phenomena such as structural rearrangements, cooperative adsorption, overshooting adsorption kinetics, or protein aggregation. In this review recent achievements and new perspectives on protein adsorption processes are comprehensively discussed. The main focus is put on commonly postulated mechanistic aspects and their translation into mathematical concepts and model descriptions. Relevant experimental and computational strategies to practically approach the field of protein adsorption mechanisms and their impact on current successes are outlined.
