Fig. 5.

agl genes in Hfx. volcanii and their putative Har. marismortui homologues are clustered to different degrees.

A. Regions of the Hfx. volcanii genome encoding Agl proteins and of the Har. marismortui genome encoding predicted Agl protein homologues are schematically presented. In addition, genes encoding predicted glycosyltransferases (GTase) near Har. marismortui aglB are shown. In each case, the genome identifier is provided above the gene while the known (Hfx. volcanii ) or predicted (Har. marismortui ) product is given below.

B. Homologous genes in the immediate vicinity of Hfx. volcanii aglD and its Har. marismortui homologue, rrnAC1873, are schematically shown. Below each gene, the current annotation is provided. In both (A) and (B), the full identifier is provided for only the first gene of a group of adjacent genes; only numbers are provided for the subsequent genes. Otherwise, the full identifier is provided. The size of each gene is considered to be equal in the scheme, as are the distances between proximal yet non-adjacent genes. Genes encoding the known (Hfx. volcanii ) or predicted (Har. marismortui ) oligosaccharyltransferase, AglB, are hatched, genes encoding known or predicted glycosyltransferases are shown in black and genes encoding proteins known or predicted to contribute to N-glycosylation are shown in dark grey. Genes encoding proteins apparently not related to N-glycosylation are shown in light grey.
