Nature park
A nature park, or sometimes natural park, is a designation for a protected natural area by means of long-term land planning, sustainable resource management and limitation of agricultural and real estate developments. These valuable landscapes are preserved in their present ecological state and promoted for ecotourism purposes. In most countries nature parks are subject to legally regulated protection, which is part of their conservation laws.
Cystathionine gamma-lyase
The enzyme cystathionine γ-lyase (EC 4.4.1.1, CTH or CSE; also cystathionase; systematic name L-cystathionine cysteine-lyase (deaminating; 2-oxobutanoate-forming)) breaks down cystathionine into cysteine, 2-oxobutanoate (α-ketobutyrate), and ammonia: L-cystathionine + H2O = L-cysteine + 2-oxobutanoate + NH3 (overall reaction) (1a) L-cystathionine = L-cysteine + 2-aminobut-2-enoate (1b) 2-aminobut-2-enoate = 2-iminobutanoate (spontaneous) (1c) 2-iminobutanoate + H2O = 2-oxobutanoate + NH3 (spontaneous) Pyridoxal phosphate is a prosthetic group of this enzyme.
