Involved in the biosynthesis of 12- and 14-membered ring macrolactone antibiotics such as methymycin/neomethymycin and pikromycin/narbomycin, respectively. Component of the pikromycin PKS which catalyzes the biosynthesis of both precursors 10-deoxymethynolide (12-membered ring macrolactone) and narbonolide (14-membered ring macrolactone). Chain elongation through PikAI, PikAII and PikAIII followed by thioesterase catalyzed termination results in the production of 10-deoxymethynolide, while continued elongation through PikAIV, followed by thioesterase (TE) catalyzed cyclization results in the biosynthesis of the narbonolide.

Miscellaneous

Type I modular polyketide synthases (PKSs) catalyze the step-wise condensation of simple carboxylic acid derivatives. Organizationally, type I PKSs are arranged into modules, wherein each module is comprised of a set of catalytic activities that is responsible for a single elongation of the polyketide chain and the appropriate reductive processing of the beta-keto functionality. A minimal elongation module contains an acyl transferase (AT) domain, an acyl-carrier protein (ACP) domain, and a ketosynthase (KS) domain. The AT domain is responsible for loading the methylmalonyl-CoA extender unit onto the phosphopantetheinylated ACP domain. Subsequently, the KS domain decarboxylates and then condenses the ACP-bound extender unit with the growing polyketide chain obtained from the preceding module to yield an ACP-bound beta-ketoacyl intermediate. In addition to the three core domains, each elongation module may contain up to three additional domains: a ketoreductase (KR), dehydratase (DH), and an enoyl reductase (ER) that are responsible for the reductive processing of the beta-keto functionality prior to the next extension step. The presence of a KR domain alone gives rise to a beta-hydroxyl functionality, the presence of both a KR and a DH domain generates an alkene, while the combination of KR, DH, and ER results in complete reduction to the alkane. Finally, a thioesterase (TE) domain, typically found at the terminus of the last elongation module, catalyzes the termination of polyketide biosynthesis. The activity of this domain results in cleavage of the acyl chain from the adjacent ACP and formation of the macrocyclic ring.2 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:i3D3910824DA5B080
