G-Amylase

Schematic drawing of monosaccharide binding sites in various glycosyl hydrolases, (a) Subsites of an endo-hydrolase, e. g., hen egg white lysozyme, (b) subsites of a disaccharide hydrolase, e. g., ((x-glucosidase, (c) subsites of a monosaccharide-releasing exo-hydrolase, e. g., glucoamylase, (d) subsites of a disaccharide-releasing exe-hydrolase, e.g., / -amylase (after [18])...

Moniruzzaman et al. [120] utilized the AFEX technique to treat corn fiber in order to enhance the saccharification by enzymes (e.g., amylases, cellulase, hemicellulase and P-glucosidase). Sugars obtained were over 80% of the theoretical yield. 

Plasma enzymes may be classified as (1) plasma-specific enzymes, (2) other secreted enzymes (e.g., amylase), and (3) intracellular enzymes. The plasma-specific enzymes include those that are secreted by some organs and have a direct action in... 

Fig, 11. Variation of the g-amylasic activity units of the samples obtained from (1) acid chloride of BIOZAN R (2) CMC acid chloride (DS 2.02) (3) trans-2,3-cellulose carbonate (4) diazotized N-(4-aminophenyl) CMC amide as a function of time. Temperature= 5°C,... 

The amounts of A chains, vhich link to a Ba chain, were analyzed by the following procedures. Here, Ba chains are defined as B chains which carry at least one A chain and the rest of the B chains are defined as Bb chains. Amylopectin is first processed into B-limit dextrin (B-LD) with sweet potato B-amylase, then with Pseudomonas isoamylase, and finally again with g-amylase (2nd B-amylolysis), successively. A chains are trimroed into roaltosyl or maltotriosyl residues depending on the even or odd numbers of the chain length... 

For nearly three decades microbial enzyme preparations have been Increasingly used as technological resources In food production, medicine as well as In other branches of national economy (Ruttloff et al , 1978 Ruttloff, 1981, 1986). Numerous enzymes are produced Industrially In tons, especially hydrolases, e.g. amylases, saccharldases, protelnases, pectln-olytlc enzymes, cellulases, lipases and others. They are still mostly used In a soluble form. 

Hydrolases hydrolyse glycosides and esters as well as peptide and other amide bonds, e.g. amylase, maltase, dextranase, lipase and trypsin.
