cysQ

Gene Synonym(s)

ECK4210, b4214, JW4172, amt, amtA[1], amtA

Product Desc.

affects pool of 3'-phosphoadenosine-5'-phosphosulfate in pathway of sulfite synthesis[2][3]

3'-phosphoadenosine 5'-phosphate (pAp) phosphatase; converts pAp to AMP; inhibited by lithium and calcium, leading to pAP accumulation; probable PAPS (adenosine 3'-phosphate 5'-phosphosulfate) 3'(2'),5'-bisphosphate nucleotidase: probably converts PAPS to[4]

Notes

[back to top]


CysQ is a main target of lithium toxicity in vivo. CysQ (AmtA) was originally thought to be involved in ammonium transport. CysQ may be part of a futile sulfur cycle with APS kinase CysC.[4]
