Rhamnogalacturonan lyase of the polysaccharide lyase family 11. The rhamnogalacturonan lyase of the polysaccharide lyase family 11 (RGL11) cleaves glycoside bonds in polygalacturonan as well as RG (rhamnogalacturonan) type-I through a beta-elimination reaction. Functionally characterized members of this family, YesW and YesX from Bacillus subtilis, cleave glycoside bonds between rhamnose and galacturonic acid residues in the RG-I region of plant cell wall pectin. YesW and YesX work synergistically, with YesW cleaving the glycoside bond of the RG chain endolytically, and YesX converting the resultant oligosaccharides through an exotype reaction. This domain is sometimes found in architectures with non-catalytic carbohydrate-binding modules (CBMs). There are two types of RG lyases, which both cleave the alpha-1,4 bonds of the RG-I main chain through a beta-elimination reaction, but belong to two structurally unrelated polysaccharide lyase (PL) families, 4 and 11.

Ciliary BBSome complex subunit 2, middle region. The BBSome (so-named after the association with Bardet-Biedl syndrome) is a complex of 8 subunits that lies at the base of the flagellar microtubule structure. The precise function of all the individual components in cilia formation is unclear, however they function to promote loading of cargo to the ciliary axoneme. The primary cilium, a slim microtubule-based organelle that projects from the surface of vertebrate cells has crucial roles in vertebrate development and human genetic diseases. Cilia are required for the response to developmental signals, and evidence is accumulating that the primary cilium is specialized for Hedgehog (Hh) signal transduction. Formation of cilia, in turn, is regulated by other signalling pathways, possibly including the planar cell polarity pathway. The connections between cilia and developmental signalling have begun to clarify the basis of human diseases associated with ciliary dysfunction. BBS2 is one of the three Bardet-Biedl syndrome subunits that is required for leptin receptor signalling in the hypothalamus, and BBS2 and 4 are also required for the localization of somatostatin receptor 3 and melanin-concentrating hormone receptor 1 into neuronal cilia.
