PE-PGRS family protein PE_PGRS16; Rv0977, (MTV044.05), len: 923 aa. PE_PGRS16, Member of the Mycobacterium tuberculosis PE family, PGRS subfamily of gly-rich proteins (see citation below), highly similar to other PGRS-type sequences e.g. AL0091|MTV004_1 from Mycobacterium tuberculosis (1125 aa), FASTA score: (45.4% identity in 959 aa overlap); Z80225|MTCY441_4 from Mycobacterium tuberculosis (778 aa), FASTA score: (51.5% identity in 750 aa overlap); etc.

Hypothetical alanine and proline rich protein; Has a dual function in uptake of nutrients and induction of host cell death. The N-terminal domain (NTD) forms an outer membrane channel and is used for uptake of nutrients across the outer membrane. The secreted C-terminal toxic domain (TNT) acts as a glycohydrolase, which hydrolyzes the essential cellular coenzyme NAD(+) in the cytosol of infected macrophages, leading to necrotic host cell death. Both functions are required for survival, replication and cytotoxicity of M.tuberculosis in macrophages.

Hypothetical protein; CRISPR (clustered regularly interspaced short palindromic repeat) is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids). CRISPR clusters contain spacers, sequences complementary to antecedent mobile elements, and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). The type III-A Csm effector complex binds crRNA and acts as a crRNA-guided RNase, DNase and cyclic oligoadenylate synthase; binding of target RNA cognate to the crRN [...]

Rv2209, (MTCY190.20), len: 512 aa. Probable conserved integral membrane protein, similar to but longer than Rv0246 gp|AL021929|MTV 034_12 Mycobacterium tuberculosis (436 aa). FASTA score: opt: 712, E(): 2.8e-32; 33.4% identity in 422 aa overlap.

ESX-1 secretion-associated protein EspK. Alanine and proline rich protein; May act as a chaperone that facilitates EspB secretion through an interaction with EccCb1.

Rv2082, (MTCY49.21), len: 721 aa. Conserved hypothetical protein. Similar to Mycobacterium tuberculosis Rv0029, and to Rv3899c and Rv3900c which may be frameshifted.
