https://www.selleckchem.com/ Bacterial lipoproteins are secreted proteins that are post-translationally lipidated. Following synthesis, preprolipoproteins are transported through the cytoplasmic membrane via the Sec or Tat translocon. As they exit the transport machinery, they are recognized by a phosphatidylglycerolprolipoprotein diacylglyceryl transferase (Lgt), which converts them to prolipoproteins by adding a diacylglyceryl group to the sulfhydryl side chain of the invariant Cys+1 residue. Lipoprotein signal peptidase (LspA or signal peptidase II) subsequently cleaves the signal peptide, liberating the α-amino group of Cys+1, which can eventually be further modified. Here, we identified the lgt and lspA genes from Corynebacterium glutamicum and found that they are unique but not essential. We found that Lgt is necessary for the acylation and membrane anchoring of two model lipoproteins expressed in this species MusE, a C. glutamicum maltose-binding lipoprotein, and LppX, a Mycobacterium tuberculosis lipoprotein. However, Lgt is not required for these proteins' signal peptide cleavage, or for LppX glycosylation. Taken together, these data show that in C. glutamicum the association of some lipoproteins with membranes through the covalent attachment of a lipid moiety is not essential for further post-translational modification.The aim was to compare the outcome of a reversed shoulder arthroplasty with a latissiumus dorsi transfer without (LD-BB) or with bone block (LD+BB) in patients with rotator cuff-deficient shoulders and combined loss of active elevation and external rotation. Postoperative patients with LD+BB were not immobilized compared to 6 weeks of immobilization in patients with LD-BB. Clinical outcome was evaluated using the Constant Score, ADLER score and satisfaction rate. Also radiological follow-up of the bone-block was performed. In total 29 patients (21 LD+BB, 8 LD-BB) were evaluated. There was no significant difference between both groups at 3 mo
