Abstract
An α-l-fucosidase (Pap-Alf) was purified from the pancreas of a starfish Patiria pectinifera by ammonium sulfate precipitation followed by several column chromatographies. The molecular mass of the purified enzyme was estimated to be 52.6 kDa by SDS-PAGE, although gel filtration analysis of the native enzyme suggests it exists as a homodimer in solution. The purified enzyme showed maximal activity at pH 5.0 and 70 °C. The enzyme was highly specific toward a fucosyl-monosaccharide (Fuc-α-pNP), but it also showed activity toward 2-sulfo-Fuc-α-pNP and fucosyl-α-lactosides (Fuc-α-Galβ1→4Glc-β-pNP). We determined the primary structure of the α-l-fucosidase and validated its expression level in starfish tissue. Whole genome sequence analysis of P. pectinifera was also performed in the present study. Detailed primary structural analysis using bioinformatics tools revealed Pap-Alf lacks the C-terminal region that is otherwise conserved in all previously described α-l-fucosidases. Quantitative gene expression analysis of Pap-Alf in each tissue indicated that the expression of Pap-Alf gene in pancreas was 5-fold higher than in ovary.

Abstract
Purpose To investigate the presence and patterns of lysosomal enzymes and mannose 6-phosophate receptor (MPRs) in human lacrimal drainage system. Methods The study was performed on healthy lacrimal sacs and nasolacrimal ducts obtained from exenteration samples immediately after surgery and frozen at -80°C for subsequent analysis. Soluble proteins' extract was used for enzyme assays, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (PAGE), native PAGE, activity staining, and western blot analysis. Membrane proteins were separately assessed for detection of mannose 6-phosphate receptors, MPR 46. Sepharose gels, 4-methylumbelliferyl substrates, and antibodies against common lysosomal enzymes and MPRs were used. Enzyme assays were carried out in triplicate to ascertain the results. Results Differential lysosomal enzyme activities were documented, and among them acid phosphatase and β-hexosaminidase were found to be high. Western blot analysis using enzyme antibodies and subsequent activity staining confirmed strong signals for moderately expressed enzymes such as fucosidase, glucuronidase, and mannosidase. Membrane extracts demonstrated the presence of MPR 46, which indicates the possible roles of cation-dependent MPRs in lysosomal targeting in human lacrimal drainage system. Conclusion This study provides a proof of principle for the presence of differential lysosomal activity and mannose 6-phosphate ligand transport receptors in human lacrimal drainage system and hypothesizes the potential implications of their dysfunctions.

Abstract
Mannose 6-phosphate (M6P)-dependent lysosomal enzyme targeting to endosome/lysosome complex is poorly understood among lower invertebrates. So far, only a M6P-independent lysosomal enzyme sorting protein, named LERP, has been described in Drosophila. Here, we have identified mannose 6-phosphate receptor (MPR) homologues in Hydra vulgaris, a basal Cnidarian, at genome level and further purified a cation-dependent MPR-like protein from hydra using affinity chromatography. Structural comparisons of hydra MPRs with mammalian MPRs confirm that the residues important for interacting with the M6P ligand are conserved. Based on our results, we report for the first time the occurrence of MPR-related proteins and M6P-dependent lysosomal enzyme targeting in H. vulgaris.
