Effect of malathion on protein synthetic potentiality of the tissues of the teleost, Tilapia mossambica (Peters), as measured through incorporation of [14C]amino acids.

The protein turnover was studied in muscle, gill and liver tissues of the fish, Tilapia mossambica, under malathion impact through the incorporation of labelled amino acids using [14C]glutamic acid, [14C]leucine and [14C]arginine as representatives of acidic, neutral and basic types of proteins, respectively. The labelled amino acid incorporation indicated the synthetic potentiality of proteins to be elevated in all the tissues of malathion-exposed (ME) fish. The results are discussed in relation to the degradative and synthetic capability of tissue proteins under malathion exposure.
