Systematic name YGR155W
Gene name CYS4
Aliases NHS5, STR4, VMA41
Feature type ORF, Verified
Coordinates Chr VII:798543..800066
Primary SGDID S000003387


Description of YGR155W: Cystathionine beta-synthase, catalyzes synthesis of cystathionine from serine and homocysteine, the first committed step in cysteine biosynthesis; responsible for hydrogen sulfide generation; advances passage through START by promoting cell growth which requires catalytic activity, and reducing critical cell size independent of catalytic activity; mutations in human ortholog cause homocystinuria[1][2][3][4][5]
