LMPD ID
LMP010096
Gene ID
837902
Species
Arabidopsis thaliana (Arabidopsis)
Gene Name
sulfotransferase 4B
Gene Symbol
ST4B
Synonyms
ARABIDOPSIS THALIANA SULFOTRANSFERASE 4B; ATST4B; ST4B; sulfotransferase 4B; T6J4.16; T6J4_16
Alternate Names
sulfotransferase 4B
Chromosome
1
EC Number
2.8.2.-
Summary
Encodes a sulfotransferase. Unlike the related ST4A protein (At2g14920), in vitro experiements show that this enzyme does not act brassinosteroids. ST4B is expressed in the roots and transcript levels rise in response to cytokinin treatment.
