11877024-5	2000	The mutation in the patients" ALAS2 gene was exon 5 A523G, causing threonine to alanine; and exon 3 T372C, leucine to proline.	Leucine	107-114	5'-aminolevulinate synthase 2	Homo sapiens	30-35	
16234850-6	2005	A database search for proteins potentially regulated by oxygen tension revealed that ALAS2 contained a sequence of amino acids (LXXLAP where L is leucine, X is any amino acid, A is alanine, and P is proline) not occurring in ALAS1, which may be hydroxylated under normoxic conditions (21% O2) and target the enzyme for ubiquitination and degradation by the proteasome.	Leucine	146-153	5'-aminolevulinate synthase 2	Homo sapiens	85-90
