Bioinformatics analysis of Holotrichia parallela PGRP-SC1. a Schematic representation of H. parallela PGRP-SC1. The transmembrane domain (TM) and PGRP homologous domain (PGRP) are indicated in wathet blue and purple boxes, respectively. b Sequence analysis of H. parallela PGRP-SC1. The domain division (TM and PGRP) are indicated above the sequences. The amidase catalytic site is underlined. The Zn binding residues are shown in red. The substrate binding site are shown in yellow shading. c The overall structure of H. parallela PGRP-SC1. The N-terminus (N), C-terminus (C), α-helices and β-strands are labeled. d Surface of H. parallela PGRP-SC1 structure. Substrate binding sites are colored green. e Phylogenetic analysis of H. parallela PGRP-SC1. The red and green circles highlight H. parallela PGRP-SC1 and the closely homologous specie PGRP, respectively. Numbers at the nodes were bootstrap values as percentage and only bootstrap values greater than 50 are shown. The same for Figs. 3-e and 4-e. Scale bar, 0.05 substitutions per site
