Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Reviewed-Annotation score:

Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein. Note that the ‘protein existence’ evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

Generates 3->3 cross-links in peptidoglycan, catalyzing the cleavage of the mDap3-D-Ala4 bond of a tetrapeptide donor stem and the formation of a bond between the carbonyl of mDap3 of the donor stem and the side chain of mDap3 of the acceptor stem. Is specific for donor substrates containing a stem tetrapeptide since it cannot use pentapeptide stems. Is thought to play a role in adaptation to the nonreplicative state of M.tuberculosis.2 Publications

Miscellaneous

The peptidoglycan structure of stationary-phase M.tuberculosis is atypical since it contains a majority (80%) of 3->3 cross-links synthesized by L,D-transpeptidases that predominate over the 4->3 cross-links formed by the D,D-transpeptidase activity of classical penicillin-binding proteins (PubMed:18408028). In fact, 3-3 cross-linkages predominate throughout all growth phases and the ratio of 4-3/3-3 linkages does not vary significantly under any growth condition (PubMed:22906310).1 Publication

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes regulatory mechanisms for enzymes, transporters or microbial transcription factors, and reports the components which regulate (by activation or inhibition) the reaction.<p><a href='/help/activity_regulation' target='_top'>More...</a></p>Activity regulationi

Is irreversibly inactivated by the beta-lactams carbapenems via the formation of a covalent adduct resulting from acylation of the catalytic Cys; ertapenem and imipenem are the most efficient drugs for in vitro LdtMt1 inactivation. Cephalosporins (cefotaxime, cephalothin, and ceftriaxone) also form covalent adducts with LdtMt1, although the acylation reaction was 7- to 1,000-fold slower and leads to elimination of one of the drug side chains. A high drug concentration (360 µM) of ceftriaxone is required for full inhibition of enzyme activity. Is not inhibited by ampicillin.3 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iE074256B6445EABC
