In molecular biology, palmitoylation is the covalent attachment of fatty acids, such as palmitic acid, to cysteine (S-palmitoylation) and less frequently to serine and threonine (O-palmitoylation) residues of proteins, which are typically membrane proteins. [2] The precise function of palmitoylation depends on the particular protein being ...
The University of Minnesota Pathway Prediction System (UM-PPS) is a web tool that recognizes functional groups in organic compounds that are potential targets of microbial catabolic reactions and predicts transformations of these groups based on biotransformation rules. Multi-level predictions are made. (bio.tools entry) [116]
Some members of the family such as ZDHHC3 and ZDHHC7 enhance palmitoylation of proteins such as PSD-95, SNAP-25, GAP43, Gαs. Others such as ZDHHC9 showed specificity only toward the H-Ras protein. [3] However, a recent study questions the involvement of classical enzyme-substrate recognition and specificity in the palmitoylation reaction. [4]
In a typical recirculating aquaculture system, a series of filtration steps maintains a high level of water quality that promotes rapid fish growth. [6] Steps include solids removal, biofiltration, oxygenation, and pumping, with each one requiring different equipment and engineering considerations.
This makes prediction difficult. [13] The recruitment problem is the problem of predicting the number of fish larvae in one season that will survive and become juvenile fish in the next season. It has been called "the central problem of fish population dynamics" [14] and “the major problem in fisheries science". [15]
In a well designed system, the existing water in the raceway is largely replaced by new water when the same volume of new water enters the raceway. Self-cleaning can sometimes be achieved if the fish stocks density is sufficiently high and the water level is sufficiently low. For example, if trout are stocked at 20 kilograms per cubic metre ...
IMTA works by creating a closed-loop system where the by-products such as excess nutrients and organic waste from fish farming, are utilized by other species such as shellfish and seaweed. This process can decrease water pollution, minimize the need for chemical fertilizers, and improve overall ecosystem health.
Aquaculture (less commonly spelled aquiculture [1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus).
