# SWISS::ACs(3pm)

## Name

SWISS::ACs

## Description

**SWISS::ACs** represents the AC (accession) lines within an SWISS-PROT + TrEMBL entry as specified in the user manual http://www.expasy.org/sprot/userman.html .

The SWISS-PROT format has recently been changed to multiple AC lines. This module will read

```
 Ordinary AC lines
    AC   P10585;
 The old temporary format (for internal use only)
    AC   Q57333; O08291; O08202; O08292; O08203; O08293; O08204; O08294;
    **   O08205; O08295; O08206; O08296; O08207; O08297; O08208; O08298;
    **   O08213;
 and the new format.
    AC   Q57333; O08291; O08202; O08292; O08203; O08293; O08204; O08294;
    AC   O08205; O08295; O08206; O08296; O08207; O08297; O08208; O08298;
    AC   O08213;
```

But, SWISS::ACs will DROP funny \*\* comment lines that are sometimes found following an AC line:

```
    AC   Q48558; P71434;
    **   MERGED 2 TREMBL ENTRIES.
```

This module will always write the new format with multiple AC lines.
