CS

Description

L-cysteine sulfonic acid synthase (CS, L-cysteate synthase) is an enzyme consisting of 419 amino acids, and its size is about 45.85 kDa. It catalyzes the conversion of O-phospho-L-serine and sulfite into L-cysteine sulfonic acid (L-cysteate) and phosphate (Fig. 1). Moreover, CS does not catalyze the production of L-cysteine due to its specificity to sulfite^[1].

Fig. 1. L-cysteine sulfonic acid synthase catalyzes the reaction that turns O-phospho-L-serine into L-cysteine sulfonic acid. CDO1, L-cysteine dioxygenase; CSAD, L-cysteine sulfinic acid decarboxylase.

Usage and Biology

The DNA sequence of CS was synthesized by IDT and was amplified by PCR. The Agarose gel electrophoresis result is shown in Fig. 2. The part has been confirmed by sequencing and has no mutations.
