This protein is involved in step 2 of the subpathway that synthesizes L-cysteine from L-serine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Serine acetyltransferase 5 (SAT5), Serine acetyltransferase 4 (SAT4), Serine acetyltransferase 2 (SAT2), Serine acetyltransferase 1, chloroplastic (SAT1), Serine acetyltransferase 3, mitochondrial (SAT3)
  2. Bifunctional cystathionine gamma-lyase/cysteine synthase (DES1), Cysteine synthase 1 (OASA1), Cysteine synthase, mitochondrial (OASC), Cysteine synthase, chloroplastic/chromoplastic (OASB), Bifunctional L-3-cyanoalanine synthase/cysteine synthase D2 (CYSD2), Bifunctional L-3-cyanoalanine synthase/cysteine synthase D1 (CYSD1)
This subpathway is part of the pathway L-cysteine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-cysteine from L-serine, the pathway L-cysteine biosynthesis and in Amino-acid biosynthesis.

<p>This subsection of the ‘Entry information’ section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries.
