Abstract
Introduction: Enzymes are important in therapeutic and commercial
procedures because they accelerate a chemical reaction to produce a useful
effect or product. The total number of pharmaceutical enzymes used
worldwide is probably more than 3000 enzymes, counting tens of thousands
of formulations containing different combinations of these substances. Most of
the industrial enzymes, including the enzymes used in the pharmaceutical
industry, are produced by fermentation of suitable microbial strains, mainly
bacteria and fungi, due to their easy handling, fast growth rate, and
appropriate scale in large vessels. Enzymes used as drugs have 2 important
features that distinguish them from conventional drugs. 1) Unlike drugs, they
bind and act on their targets with high affinity. 2) are highly specific and act as
catalysts to convert multiple target molecules into desired products. These
two properties turn enzymes into special and powerful drugs that can perform
biochemical treatment in the body that the synthetic active ingredient cannot
do. Several enzymes are used to prevent and treat common diseases such as
heart attack and stroke, for example, collagenase enzyme is used to heal
burn wounds and chondroitinase enzyme is used to treat spinal cord injury.
Lysosomes are naturally used as an antibacterial agent in foods and
consumer products, due to their ability to break the carbohydrate chains in the
bacterial wall. It has also been shown that they have anti-HIV activities
because they have RNaseA and RNaseU and selectively destroy viral RNAs,
and they have presented exciting possibilities in the treatment of HIV
infection.
Methods: Chemical immobilization of proteins and enzymes was first
performed in the 1960s and is an emerging approach for new drug therapies.
Immobility means enzymes that have limited mobility or become less mobile
due to chemical or physical treatment. The industrial use of enzymes is very
limited, because they are very unstable, have a high purification cost, and
after the completion of the catalytic process, they have a laborious process of
recovering the active enzyme from the reaction mixture. Immobilized enzymes
are more stable against pH, temperature stress and are less sensitive to
denaturing agents. In addition, an immobilized (immobilized) enzyme should
have long-term stability and unchanged biological activity and sensitivity
compared to the free enzyme after binding to the matrix if used as a
therapeutic target. Immobilization was used for studies with enzymes such as
