cdc25 | M-phase inducer phosphatase; This protein functions as a dosage-dependent inducer in mitotic control. It is a tyrosine protein phosphatase required for progression of the cell cycle. It may directly dephosphorylate p34(cdc2) and activate the p34(cdc2) kinase activity. (596 aa) | ||||
pyp1 | Tyrosine-protein phosphatase 1; Plays a role in inhibiting the onset of mitosis. Dephosphorylates sty1/spc1 and wis1/spc2/sty2. (550 aa) | ||||
SPACUNK4.09 | Uncharacterized protein UNK4.09. (339 aa) | ||||
rdl2 | Putative thiosulfate sulfurtransferase, mitochondrial; Thiosulfate sulfurtransferase which catalyzes the transfer of sulfane sulfur from thiosulfate to cyanide. (142 aa) | ||||
tum1 | Probable 3-mercaptopyruvate sulfurtransferase; Required for formation of the 2-thio group of the 5- methoxycarbonylmethyl-2-thiouridine modified base in some tRNAs. (298 aa) | ||||
ibp1 | Dual specificity phosphatase ibp1; May play a role in DNA replication checkpoint via regulation of hsk1 or may act downstream of hsk1 in an S phase regulatory pathway. (138 aa) | ||||
pyp2 | Tyrosine-protein phosphatase 2; Plays a role in inhibiting the onset of mitosis. Dephosphorylates sty1/spc1 and wis1/spc2/sty2. (711 aa) | ||||
uba42 | Adenylyltransferase and sulfurtransferase uba4; Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln). Acts by mediating the C-terminal thiocarboxylation of sulfur carrier URM1. Its N-terminus first activates URM1 as acyl-adenylate (-COAMP), then the persulfide sulfur on the catalytic cysteine is transferred to URM1 to form thiocarboxylation (-COSH) of its C-terminus. The reaction probably involves hydrogen sulfide that is generated from the persulfide intermediate and that acts as nucleophile towards URM1. Subseque [...] (401 aa) |
