General annotation
FunctionCatalyzes the extradiol cleavage of 3,4-dihydroxy-9,10-seconandrost-1,3,5(10)-triene-9,17-dione (3,4-DHSA)
Product3,4-DHSA dioxygenase
CommentsRv3568c, (MTCY06G11.15c), len: 300 aa. HsaC, highly similar to e.g. Q9KWQ5|BPHC5 from Rhodococcus sp. RHA1 (300 aa), FASTA scores: opt: 1715, E(): 3.8e-103, (82.15% identity in 297 aa overlap); O50479|EDOB from Rhodococcus rhodochrous (300 aa) FASTA scores: opt: 1714, E(): 4.4e-103, (82.5% identity in 297 aa overlap); O69359|BPHC6 from Rhodococcus erythropolis (300 aa), FASTA scores: opt: 1647, E(): 9.1e-99, (78.25% identity in 299 aa overlap); Q9RBT2|BPHC1 from Pseudomonas sp. SY5 (301 aa) Pseudomonas sp. SY5 (298 aa) FASTA scores: opt: 767, E(): 3.9e-42, (42.8% identity in 299 aa overlap); P47228|BPHC_BURCE from Burkholderia cepacia (Pseudomonas cepacia) (297 aa), FASTA scores: opt: 670, E(): 6.8e-36, (40.55% identity in 296 aa overlap); etc. Contains PS00082 Extradiol ring-cleavage dioxygenases signature. Belongs to the extradiol ring-cleavage dioxygenase family.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011).
OperonRv3569c and Rv3568c, Rv3568c and Rv3567c are co-transcribed in M. bovis BCG, by RT-PCR (See Anderton et al., 2006).
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
